what are the disadvantages of a fuel cell car?

Answer 1

a disadvatage is that it hasnt been made yet and it is slow.I think lols

Answer 2

Interesting that you should ask for their disadvantages at a time when companies are investing heavily in their development. But as with all things, they do have disadvantages. One of them is that most fuel cell concepts foresee the use of hydrogen, which is actually not really a wise fuel to use, since it costs so much other resources to generate it in the first place. But that's only the case with hydrogen-powered fuell cells. A fuel cell can be powered by anything at all, even olive oil if you wish. At that stage, a car with a fuel cell drive basically becomes an electric car which has a little doodad full of olive oil instead of a battery, and which makes great use of that olive oil to generate electricity for its primary drive engine. The disadvantage, I guess, is that you still need to burn some type of fuel to run that kind of car - so, it's still not really zero-emission. But it's more efficient than anything else out there.

Answer 3

Disadvantages: Physics make it pretty much impossible.

Water is the lowest energy state of hydrogen in abundance on earth, and is where the H2 would have to be produced from, so to change it to higher energy H2 would require large energy inputs which due to mechanical and chemical inefficiencies cant be gotten back out of it. It defies the laws of physics, particularly the law of conservation of energy.

H2 powered cars are pretty much unfeasable, as they use more energy than they make, so it would end up just using MORE gas (via powerplants and such to do electrolosys on the water) than they could ever save.

Only Bill Gates can afford it.
