it squirts hydrogen throgh a fuel cell to make electricity to power the car
No, fuel-cell automobiles do not use gas as a fuel. They use hydrogen gas as a fuel source, which is converted into electricity to power the vehicle.
a fuel cell is a cell that produces electricity they are used to provied power and water for the spacecraft so the space craft could'nt really survive with out fuel cells
as electricity. If hydrogen fuel cell cars make it may be delivered at your filling station as liquid hydrogen.
A fuel cell car would be defined as a vehicle with an electric motor or engine that uses a fuel cell to produce electricity to power its motor with hydrogen.
Fuel cells and batteries are similar because they use a chemical reaction to provide electricity. A battery stores the chemical reactants, usually metal compounds like lithium, zinc or manganese. Once used up, you must recharge or throw away the battery. A fuel cell actually creates electricity through reactants (hydrogen and oxygen) stored externally. The fuel cell will produce electricity as long as it has a fuel supply. In short, a fuel cell vehicle is refueled instead of recharged.
I expect you are thinking of hydrogen. It's not that we don't have plenty of ways to make it, indeed we do that, in vast quantities, to manufacture fertilizers, margarine etc. The problem is that we make it from natural gas, a fossil fuel, and there's no point to the fuel cell if it doesn't replace fossil fuel use. We can also make hydrogen by electrolysis, but that requires electricity, and therefore a way of making electricity, so doing that without burning fossil fuels becomes the issue.
Because a fuel cell converts the chemical energy of a fuel and an oxidant into electricity. This means that the space craft uses this electricity to work. It is basically like a giant battery which powers the space craft. Hope this answers your question.
You probably mean a fuel cell, which is a device for combining a fuel (usually hydrogen) with an oxidizer (usually oxygen), creating electricity (and some waste heat).

A fuel cell type battery is the most efficient type of electricity generation.
Energy+Metal=Electricity or Sun+Solar Cell=Electricity
