Hydrogen gas
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.
Fuel cells come in many varieties. Low-temperature designs such as proton exchange membrane fuel cells [PEMFC's, also known as polymer electrolyte membrane fuel cells] are mostly aimed at portable and transport applications
Fuel cells operate by combining hydrogen and oxygen without actual combustion as in gasoline engines. A catalyst separates the electrons and protons to combine the elements. (Some versions of fuel cells are high-temperature only.) Hydrogen gas

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.
You'd need to drop your fuel tank and drain it out.
