Can a Fuel Cell Vehicle Use Other Fuels Besides Hydrogen?
Fuel cells run on hydrogen, the most abundant element on Earth. The simplest and most efficient vehicle designs store hydrogen on board, either as compressed gas, liquid, or in metal hydride. Many automotive manufacturers have used a transition fuel in earlier models of their fuel cell vehicles, with the long-term vision of strictly hydrogen-powered vehicles. Some have demonstrated vehicles running on methanol and sodium borohydride. The very first FCVs in demonstration are powered by hydrogen. They are fleet vehicles that refuel at a centrally located fuel station.
