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.

The hydrogen in the Sun is fuel for the nuclear fusion reaction.
the product in hydrogen cells is not a greenhouse gas can also be: The product in the fuel cell reaction is not a greenhouse gas - apex :)
fossil fuel may be depleted soon. but hydrogen gas can me made available. also, if there are cheaper ways to split water into hydrogen and oxygen, then the better it is as water is available everywhere ----------------------------------------------------------------- Fuel cells produce hydrogen gas from fossil fuels, and renewable fuel sources. Hydrogen can also be made from other energy (electric) sources and electrolysis of water, but compressing and transporting it poses it's own problems. Despite this, the production of hydrogen as a fuel source uses more energy than can be gained from the hydrogen itself.

The term for a fuel made only of hydrogen and carbon is hydrocarbon, the simplest of which is methane gas CH4.
The fuel cell hydrogen is one of the two gasses, that are created by the seperations of a water molecule H2O. A water molecule consists of H - hydrogen, and O - oxygen. A fuel cell hydrogen is the gas created by the separation of a water molecule with the help of a fuel cell.
Solid fuel: coal, wood Liquid fuel: kerosine, gasoline Gas fuel: methane, hydrogen
Hydrogen can't be stored in conventional fuel tanks because it is a gas at normal temperature and pressure.
