Fuel Cell

A device that converts chemical energy from a fuel (like hydrogen) and an oxidant (like oxygen) directly into electrical energy, producing water and heat as byproducts.

TECHNICAL DEFINITION

An electrochemical device that continuously converts the chemical energy of a fuel (e.g., hydrogen) and an oxidant (e.g., oxygen) into electricity through a controlled reaction, without combustion, commonly used for power generation in spacecraft and electric vehicles.

BACKGROUND

A hydrogen vehicle is a vehicle that uses hydrogen to move. Hydrogen vehicles include some road vehicles, rail vehicles, space rockets, forklifts, ships and aircraft. Motive power is generated by converting the chemical energy of hydrogen to mechanical energy, either by reacting hydrogen with oxygen in a fuel cell to power electric motors or, less commonly, by hydrogen internal combustion.
