Richard asks…
I need HELP and FAST!!!!!!?
this is a project for school…..we are researching allternitve fuel sources…..can you tell me….
1) how expensive it would be to repair a hydrogen fuel cell car
2) how efficient is a hydrogen fue cell cars engine?
3) what kind of options can you get with a mercedes and a mercedes with the hydrogen
4) would it be a manual transmission or otherwise?
5)how long will that battery last in a hydrogen car?
k, thats it PLEASE HELP with as much info as you can
AND DONT ANWSER IF YOU’RE NOT SERIOUS
THANKS SOOOO MUCH!!!!

1) It depends on how many there are. If everyone has a hydrogen car, repairs would cost as much as repairs to a gas car. If there are only a couple on the road, you better have a fat wallet or a good warranty.
2) Once again, it depends. However, energy wise a hydrogen car would not be very efficient at all. Hydrogen takes alot of energy to make because it doesn’t occur as a stand-alone molecule on Earth. You either have to separate it from hydrocarbons (fossil fuel) or separate it from H2O (water). Right now almost all of our hydrogen comes from fossil fuels. If you get it from water, you pay a huge energy penalty: about 50% of the energy you put into the water is used up in the separation process. The bottom line is that efficiency is NOT an advantage of hydrogen. The real advantage is in it’s abundancy and it’s potential as a clean source of energy. Hydrogen is the most abundant element in the known universe, so we would (probably) never run out of it. Potentially, we could set up plants where wind or solar plants use the electricity they generate to electrolyze water, which would make hydrogen almost 100% emmission free.
The problem then becomes availability of clean fresh water, which is rapidly becoming as serious an environmental issue as Global Warming.
3) I would check BMW’s website. I believe their hydrogen car is just like their other cars, but with a hydrogen tank and a gasoline tank so you can choose what to use at the pump. You pay more and the car is heavier. I don’t think Mercedes offers a hydrogen car. Also take a look at Honda’s FCX, which they say they will offer soon. The difference between those cars is in their engines. The BMW actually burns the hydrogen, whereas the Honda uses it to power a chemical reaction inside a fuel cell, which generates electricity to run the vehicle. Essentially, it’s an electric car that uses a fuel cell instead of a battery. Google “BMW Hydrogen Car” and “Honda FCX”
4) The Bimmer I think uses either manual or automatic. The Honda uses something called a CVT, or Continuous Variable Transmission. There would be only 3 “gears”, forward, reverse and park. Since most people only use Drive, Reverse and Park in an automatic, the only difference you would notice when driving the FCX is that there would never be any gear shifting from the transmission.
5) As long as you keep putting hydrogen or water into it
Good luck!
James asks…
Which country supplies Britain with Oil?
Hi.
For my GCSE Chemistry Casestudy. i have chose to discuss this argument
‘ is hydrogen fuel the answer to global warming’.
I am on the Pros of this question. One of the pros is that if hydrogen cars were to be more used then disputes over oil will decrease as the demand for it will be less.
Along with answering the question stated as the title, do u have any more pros. Some already which i have are
-> the by- product is only water
-> Hydrogen CAN be made from a renewable source
do you have any more
thanks

Noise reduction.
Partial pollution reduction in towns.
Lighter than a battery.
Rapidly refueled (compared to a battery)
More efficient than combustion engine.
Look up fuel cell in wikipedia there are lots of different fuel cells that use hydrogen.
