No, fuel cells consume fuel; effectively they are oxidising it in order to make electricity directly. For a hydrogen fuel cell, you still need to add hydrogen when it runs out. Whereas a battery (in the accepted usage of the word) is self-contained - electricity can be pumped in to recharge it, but no fuel.
- _hypx 4y agoFuel cells do not consume fuel. It converts hydrogen and oxygen into water. You can reconvert water back into hydrogen and oxygen. You can conceive of a fully closed-cycle system for this. But it's not worth it, since you are just carrying a big tank of water for no reason. It is a smarter solution that a battery which does carry everything at all times.
