Not only do fuel cells use hydrogen and oxygen (air) as their source of energy but they use fuel much more efficiently.

For instance, standard gas-driven engines are only 22 percent efficient. In other words 22% of the fuel used actually goes to powering the engine. The 78% which is left is lost to heat.

Diesel engines are a tad better, coming in at 27% efficient.  Hybrid electric powered cars are getting better at about 30-35%. Fuel cells can be expected to be about 55 per cent efficient.
