Will Biofriendly Fuel Cells Power Future Cars?

Article by Peter Verhoeff

At the November 2007 Los Angeles Auto Show, Honda unveiled its new biofriendly FCX Clarity fuel cell vehicle (FCV). Honda plans to lease a limited number of them in the summer of 2008. First developed in 1999, the 2008 model has many improvements, such as a 30% increase in driving range and a 25% increase in power-to-weight ratio. (1)What makes FCVs attractive, compared to gasoline-powered cars, is that fuel cells use hydrogen as a fuel to produce electric power, with pure water as the only byproduct. This makes the FCV a perfect zero-emission vehicle, emitting no greenhouse gases or air pollution whatsoever. Other advantages include reduced dependence on fossil fuels, better energy efficiency and greater design flexibility.

Typically, an FCV has an on-board tank of hydrogen gas, while the needed oxygen is drawn from the surrounding air. In “burning” the hydrogen, the fuel cell produces electricity that powers one or more electric motors to drive the wheels.

Hydrogen is the most abundant chemical element in the universe. Unfortunately, most of it is combined with other elements, as with oxygen to form water, or with carbon to form organic compounds, such as coal, oil and natural gas. Hydrogen can be extracted from water, using a process called electrolysis, but this method uses electricity. As power stations generally use fossil fuels, this makes electrolysis a less than optimum solution.

National Geographic magazine mentions a different method of generating hydrogen. Researchers Logan and Cheng of Penn State University were able to extract 99% of available hydrogen from organic materials using bacteria. This new method of extracting hydrogen is not yet commercially viable, but is promising as it does not require much energy to produce the fuel, giving it a distinct advantage over ethanol and other biofuels. (2)

If the challenges of cost, fuel distribution and delivery can be overcome, fuel cell vehicles promise to become a way to combat energy dependence, fossil fuel depletion, air pollution and greenhouse gas emissions. However, while most vehicles are still gasoline-powered, and will be for some time, it is important to make more efficient use of what fuel we have. This will buy time for the needed research and establishment of better energy solutions.

For that purpose, Biofriendly Corporation has created Green Plus®, a liquid fuel catalyst that causes more complete burning, resulting in fewer harmful emissions and better fuel economy.

Gm Readies Fuel Cell Technology for Future Production


General Motors Corp. is looking to advance its fuel cell ambitions to another level by moving more than 500 fuel cell experts from advanced development laboratories to core engineering functions to prepare this technology for future production.

According to media reports, more than 400 fuel cell engineers are set to report to GM’s Powertrain Group to begin production engineering of fuel cell systems. Another 100 will transfer to GM’s Global Product Development organization to begin integrating fuel cells into future company vehicles. Finally, more than 150 fuel cell scientists and program support will remain as part of GM’s Research and Development center to continue advanced research in hydrogen storage, fuel cells and program commercialization.

The move is aimed at speeding up the company’s efforts to produce vehicles that displace petroleum through energy diversity.

According to Larry Burns, GM Vice President, Research and Development, “Eight years ago we said that hydrogen fuel cell electric vehicle technology could make a major contribution to solving the energy and environmental challenges facing the automobile industry.” The announcement, Burns adds, signals another important milestone as GM moves fuel cell vehicles closer to future production.

GM, maker of quality GMC window regulator, gave the details about its fifth-generation fuel cell system technology when it unveiled the fuel cell-powered E-Flex version of the Chevrolet Volt at the Shanghai Auto Show last April. This latest system is half the size of its predecessor, yet provides the same power and performance.

This realignment is yet another initiative in GM’s commitment to displace petroleum usage in the auto industry through a range of propulsion alternatives, including:

• E85-capable biofuel vehicles – GM is a leading producer with more than 2 million on the road today

• GM’s 2-mode hybrid system for large city buses

• GM’s Hybrid System in the Saturn Vue Green Line and Saturn Aura Green Line

• Coming this fall, GM’s 2-mode hybrid system in the Chevrolet Tahoe and GMC Yukon full-size SUVs, which provides a more than 25-percent improvement in fuel economy to what is already the industry’s most fuel-efficient large SUVs, with no compromises in performance or towing capability

• Due next year, a front-wheel-drive 2-mode Saturn Vue Green Line that is expected to deliver up to a 45-percent improvement in combined city and highway fuel economy compared with the current non-hybrid Vue, based on current federal test procedures

• Plans to produce a plug-in version of the 2-mode hybrid Vue Green Line that has the potential to achieve double the fuel efficiency of any current SUV

GM’s fourth-generation system currently powers the Chevrolet Sequel and Equinox Fuel Cell vehicles. The Sequel recently went into the record books as the first electrically-driven fuel cell vehicle to achieve more than 300 miles on one tank of hydrogen, in and out of traffic on public roads, while producing zero emissions. The Chevrolet Equinox Fuel Cell will be launched later this year as part of Project Driveway, which will place more than 100 hydrogen fuel cell vehicles with consumers in New York, Washington, D.C. and Los Angeles.

Question by Jessie: Why manufactured try to use hydrogen fuel cell this technology in their industry?

why manufacture want to use hydrogen fuel cell built a car?

Best answer:

Answer by racer123
This tech has proven so far that it is ultra-expensive with a very limited life, thus it must be subsidized to even compete with low-tech battery/solar tech. Manufacture’ers are after the big millions of $ from governments willing to dish it out. Why you ask? -To pocket the money and keep their co’s wealthy. This tech has proven it’s-self,so far, a money pit deeper than the marrianna trench. Why do some governments continue to fund it? It’s all about keeping that underground bunker supplied with electricity-after the bombs have been let loose.

Is hydrogen the car fuel of the future?

Recently the World Nuclear Association announced that, by 2050, the world’s vehicles would all run on hydrogen. Given that today’s motoring industry produces vehicles that are largely run on petrol and diesel, with a small percentage of electric cars too, this prediction may seem way off the mark and a bit like something out of Back To The Future; however it could be more accurate than it seems. Produced by the world’s nuclear power stations, hydrogen could be a pollution-free alternative to run the world’s cars on.

The environmental message which resonates around the globe today is to cut down on global warming by producing less carbon dioxide emissions and, whilst this will slow down the affect of global warming, consumers also need to reduce their reliance on traditional fossil fuels, like gas and oil too. Of course, for people to be able to choose to ‘go green’, they need the option to do so first, so manufacturers in essence need to be the ones to make the first move towards less pollution.

Hydrogen has been suggested as the best alternative to the world’s reliance on fossil fuels and it can hopefully ‘plug the gap’ between reliable but polluting fuels like oil and greener energy, like wind power, which is currently not as efficient as it needs to be to seriously impact the world’s energy supplies. Obviously there would be pollution and waste from nuclear power stations when they produce hydrogen, but it is still far more environmentally friendly as it does not create more pollution when it is subsequently burnt later on.

The greenest way to produce hydrogen today is through the energy created by solar and wind power, which in turn can be used to produce electrolysis to turn water into hydrogen or, alternatively, current nuclear power stations could be made larger to accommodate the hydrogen production process. Initially this would work by using any excess electricity created to produce hydrogen relatively cheaply, from where it could be distributed to either a separate national grid, or indeed be delivered directly to filling stations, much like today’s petrol stations.

In fact, car manufacturers announced plans to create a hybrid car which runs on electricity and hydrogen but, obviously, the car is only at the concept stage so far, as there are no convenient ways to refill on hydrogen. However, the immediate benefit of a car like this would be that, once burnt, the hydrogen fuel would simply recombine with oxygen, producing pure water as waste. Hybrid cars like this will probably be how hydrogen is introduced into the motoring industry, much like how electric cars were introduced through successful hybrid designs.

Better still, motorists can even buy a special hydrogen kit system for their car today, which can be easily fitted and essentially means the cars runs on water and electricity, so the car simply needs to be ‘charged up’ whenever it starts to run out of electricity. Garages will no doubt soon see an influx of motorists looking to have hydrogen kits fitted to their cars, as simply as they would replace a cracked windscreen or change a wheel.

Question by Are you ready for some….: How long before hydrogen fuel is available at gas stations.

I love the idea of fuel cell vehicles, but gas stations will want the government to pay for conversions. Why haven’t the wheels been turning on this already. It is going to happen. The arab world is total control of our economy because of our dependance on foreign oil. American owned oil companies could help by adding refineries, but they would prefer that the government build for them (welfare for the billionares). Why don’t OUR elected officials cut there nuts off & start funding hydrogen production. Exxon & the Saudi’s can pound sand up each others arses while they wait for somebody to buy their product.

It seems like hydrogen fuel cells were all the hype a few years ago, and now everyone wants to turn to natural gas. Why? Is natural gas that much better or cheaper?

Best answer:

Answer by feels so gud 2 be true
it’s better and the price depends. the carbon emission is lesser using natural gas. hydrogen fuel cells is not good as oil or bio-diesel in running cars.

On the Horizon: Future Fuels

Between elevated gasoline prices (which show every indication of staying that way) and the current concern about the environmental impacts of vehicle emissions, you’ve probably been hearing a lot of discussion about the use of “alternative fuels.” It sounds like a good idea, you think…but do you know what alternative fuels are actually in the running? Here’s the shortlist of the alternative fuels to keep an eye on, and a major advantage and disadvantage for each:

Electric

Electricity is a source of power that we already produce, store, and use. To power an electric vehicle (EV), electricity is produced by a power plant or other standard means and is then stored in the battery that will operate the vehicle.

Pro: A vehicle powered solely by electricity produces no emissions.

Con: In current models, batteries need to be recharged frequently.

Biodiesel

Biodiesel is a fuel that is made from vegetable oils and animal fats through a chemical process called esterification. When the oils and fats are mixed with alcohol, their molecules break down into methylesters, which are then used as fuel, and a waste product of glycerin. It can be used in some diesel vehicles with very little, if any, modification to the existing engine.

Pro: Potential fuel sources vary from grain crops to used cooking grease.

Con: Biodiesel thickens and freezes at low temperatures.

Ethanol

Ethanol is a type of alcohol that is created through the fermentation of substances with high starch or sugar contents, such as corn or sugar cane. In this process, yeast bacteria consume the sugars and starches and produce carbon dioxide and ethanol as by-products. The use of chemical catalysts can be used to make the process faster and more productive.

Pro: Ethanol can be produced from renewable agricultural resources.

Con: Contains less energy than the same amount of gasoline.

Hydrogen Fuel Cells

Hydrogen fuels cells harness the electrochemical reaction between hydrogen and oxygen. The bonding of hydrogen and oxygen atoms results in two products: energy, which is then stored as power in the cell, and—you guessed it: water.

Pro: Hydrogen engines are typically more efficient than gasoline engines.

Con: Current vehicle designs can only store enough hydrogen for short-range travel.

At first, you’ll most likely see these fuels used in combination with current gasoline-engine technology. Hybrid electric vehicles (HEVs) utilize both a standard gasoline engine and a rechargeable battery, and are already offered by several car manufacturers. Hybrid vehicles with a gasoline engine and a hydrogen fuel cell are currently in development, and are estimated to hit the market in 2008 to 2009. Vehicles that are designed or modified to run on mixtures of gasoline and biodiesel or ethanol show promise, and are already in use.

While some types of alternative-fuel vehicles aren’t yet readily available to the public, keep your eyes open—a combination of research, public encouragement, and lively market competition brings that day ever closer. Honda and Toyota, the first automotive manufacturers to market HEVs in the United States, have already been joined by a handful of others…and the rest are likely to follow suit.

What Hydrogen Means For Your Future

Article by GARKO NOVIS

The Hydrogen Economy is the term used to mark the shift from fossil fuels such as petroleum and diesel to hydrogen. The postulate of a Hydrogen Economy is one of an unlimited energy source that would be used to generate energy without allowing pollutants into the air.

Unfortunately our current scene is a “hydrocarbon economy” but the process in the direction of a “Hydrogen Economy” has already begun. At a not too distant date in the future we will have freed the society from carbon and we will be living in a new age facilitated by the “Hydrogen Economy” which will get its energy from renewable resources. Hydrogen energy will be even more available than the access you now have to petroleum, natural gas, and electric power.We can already see some cities, such as Chicago and Los Angeles that have powered by hydrogen fuel cells. Ford, GM, BMW, Toyota, and Honda have prototype cars powered by hydrogen. Ford chairman William Clay Ford Jr. has proclaimed that the fuel cell will “finally end the 100-year history of the internal-combustion engine.”

Hydrogen is the solution that has the incredible potential to do for the availability of energy sources what the personal computer and the Internet have accomplished for the information revolution. Global reliance on Middle East oil will come to an end and global trade balances will be restructured. Fuel cells are the pivotal piece of technology which will bring a complete upheaval in the energy sector and restructure the direction of history.The Hydrogen Economy is a bright vision for a peaceful and prosperous future freed from the addiction to energy sources in the world’s most turbulent regions. I view hydrogen as the power generation fuel of the future that will get the world out from under the yolk of fossil fuels and Big Oil corporations, clean the environment, and lift billions out of hunger and destitution. If major change is desired, government and individual cohesion must be fostered to put the focus on development efforts. Plans are needed to ensure the Hydrogen Economy vision becomes a reality soon.But we need not wait for that…WATER4GAS is offering information for a nominal fee which car owners can use in their garage or wherever to create a small device which instills hydrogen into the gasoline/air mixture that their vehicle runs on.What this does is make smaller particles out of the particles that the engine burns as fuel. Therefore the system is able to use a lot more of the gas.By doing this you can minimumly expect to lower your gasoline usage by 30-50% or even more. Those particles must have been pretty “blankin’” huge in some engines before. But with W4G they are made consumable so you can lower your gasoline usage.It also helps to lower emissions significantly.This package of info has been purchased by over NINE THOUSAND car owners already and the percentage of happy customers is about 99%! So how about you?———-

Question by Alex: I am doing a science project on hydrogen fuel rockets and I have the kit.?

What is the equation for the reaction of citric acid and water? Again this is from a Hydrogen Rocket fuel kit and the kit contains: citric acid, batteries and the launch system.

Best answer:

Answer by Shadow
Is there anything else in the kit?

Citric acid merely dissolves in water (it doesn’t react with it).

I’m not sure how the kit is supposed to function, but can imagine two possibilities:

1) If there’s an active metal like zinc in the kit, then it’d be possible to produce hydrogen from your citric acid solution (citric acid + zinc –> zinc citrate + hydrogen).

2) It’s also possible to use the batteries to electrolyze the water (split it into hydrogen and oxygen) by electrolysis. In that case, the citric acid is just serving as an electrolyte.

Without knowing more about the kit, though, it’s hard to say more. If it’s electrolysis, though, the equations can be had from Wikipedia:

In the water at the negatively charged cathode, a reduction reaction takes place, with electrons (e−) from the cathode being given to hydrogen cations to form hydrogen gas:

Cathode (reduction): 2H2O(l) + 2e− → H2(g) + 2OH−(aq);

At the positively charged anode, an oxidation reaction occurs, generating oxygen gas and giving electrons to the anode to complete the circuit:

Anode (oxidation): 2H2O(l) → O2(g) + 4H+(aq) + 4e−;

Combining these two reactions yields the overall decomposition of water into oxygen and hydrogen:

Overall reaction: 2H2O(l) → 2H2(g) + O2(g)

The number of hydrogen molecules produced is thus twice the number of oxygen molecules. Assuming equal temperature and pressure for both gases, the produced hydrogen gas has therefore twice the volume of the produced oxygen gas. The number of electrons pushed through the water is twice the number of generated hydrogen molecules and four times the number of generated oxygen molecules.

Fuel Cell Vehicles – Zero Emission Vehicles of the Future

Zero emission vehicles are the future. One that we haven’t seen much of is the fuel cell powered vehicle. Fuel cells have been used on space crafts for many years. A vehicle that is considered zero emissions is one where the fuel cell is fueled by Hydrogen, and it has to be 100% hydrogen.

Fuel cell vehicles turn hydrogen fuel and oxygen into electricity. Cars with an electric motor can then be powered by using this electricity. This can be compared to traditional vehicles where the electricity from batteries power the motor in an electric vehicle. The combination of oxygen and hydrogen produces energy and water. In fuel cells, this can be accomplished without using any burning or combustion.

These cars are considered zero emission vehicles because the exhaust from these cars  comes out as water vapor and steam. If the fuel cells didn’t get as hot as they do, water would just pour out of the exhaust pipe. But fuel cells get VERY hot, so it comes out as water vapor or steam. We have known of this technology for a long time though. Think of it like a space shuttle. Space shuttles are fueled with liquid oxygen and also liquid hydrogen. Then they are mixed together and ignited to cause a ridiculously hot fire which then propels the spacecraft into their air because of the expanding gases. This is what causes them to fly.

We know of a number of ways that can provide hydrogen to a fuel cell. One way is to simply put hydrogen gas and also air into the fuel cell itself. In order to carry hydrogen gas like this, it needs to be compressed. This is usually to about 3000 lbs per square inch. In order to do this, special containers need to be used.

Another way of providing hydrogen gas is to hold it on the car in the form of a liquid. In order to create hydrogen it needs to be made cold and also compressed. Hydrogen in liquid form is VERY cold. It is around 423 degrees below zero. The containers that hold this freezing cold liquid need to be well insulated and kept very safe. By warming up the liquid, or even lowering the pressure, you can release the gas into a fuel cell which will be able to power the vehicle that it is in.

Another very popular method of getting hydrogen to a fuel cell is using a reformer. A reformer is a device that can take out the hydrogen from hydrocarbon fuels. These are methanol or gasoline. When something other than hydrogen is used, the fuel cell is no longer zero-emission but it still may have extremely low emissions.

It is common to hear people talking about how fuel cell vehicles could be the future. What people don’t know is how far away we are from making these reasonably priced. High class families would have trouble affording these vehicles.

Question by gregory_s19: What will it take to get fuel-cell vehicles on the road nationwide?

Hydrogen-fueled vehicles (fuel cell cars) cause no geenhouse gases. And hydrogen will never be exhausted. So what are we waiting for?

Best answer:

Answer by dana1981
Lots of things.

First, we need an environmentally friendly and cheap source of hydrogen. Your claims that they cause no greenhouse gases is incorrect, because the hydrogen has to come from somewhere. The only reasonably efficient method we have of getting hydrogen right now is from natural gas, and the process emits as much CO2 as burning gasoline.

Theoretically you can get hydrogen from water, but you have to break the atomic bonds, which requires a ton of energy. At the moment it takes a lot more energy than you’re going to get out by burning the hydrogen.

Secondly, even if we had a good source of hydrogen, we have no infrastructure to transport it and store it. You have to have an easy way to refuel the hydrogen fuel cells. Building such infrastructure will cost billions of dollas, and who’s going to pay for that?

Especially since electric cars are becoming advanced, are more environmentally friendly, and the infrastructure (power grid) is already in place.
