I have read a design of a car moved by fuel cells, using Hydrogen from water. This is my question:
In the system they used solar cells to generate electricity and separate H from water. Then this H was used to feed the fuel cells.
So… Is the energy generated from one gram of H by the fuel cell greater than the energy consumed to separate H from water? Is that possible? What about the efficiency? It wouldn’t be better to run the car from the solar cells?

Or if it’s the opposite… Can I think about a fuel cell that produces its own fuel? So there is no need of refilling?

How much oxygen per pound of hydrogen is used that ***** out of the air?
