such as hybrids which use fuel cells
The so-called "hybrid" cars are gas/electric. They still pedominantly run on octane (gas) but can also store the energy usually lost in braking (a process called regenerative braking) and use this stored electrical energy for acceleration (the process that consumes fuel greatest).
The so-called "fuel cell" cars that are being used in large numbers in Iceland run on electrical energy that is produced during the conversion of hydrogen and oxygen into water.
