fuel cells work as long as their is a constant supply of hydrogen and oxygen but you can't possible store a never ending supply in your car, do they have to put more in? How does this process work? And how does the electrical current used to do work outside the cell and then how does it return to the fuel cell? so confused?
definite you are able to make electrical energy by potential of burning hydrogen. although the present problems in contact are particularly with the storage of hydrogen, somewhat than the honestly combustion of hydrogen in engines.
The key here is that they are called fuel cells. The hydrogen and oxygen are replenished at a fuel station just like gasoline for your car. These cells work like a battery. The cell has two terminals a plus and a minus. Individual cells are connected in series to get the desired operating voltage. No need to feel confused, this is very new technology and needs a lot of development to become practical.
