fuel cell

n.
An electrochemical cell in which the energy of a reaction between a fuel, such as liquid hydrogen, and an oxidant, such as liquid oxygen, is converted directly and continuously into electrical energy.

fuel cell

n
(Chemistry) a cell in which the energy produced by oxidation of a fuel is converted directly into electrical energy

fu′el cell`


n.
a device that produces a continuous electric current directly from the oxidation of a fuel, as that of hydrogen.
[1920–25]

fuel cell

A device that produces electricity by combining a fuel with oxygen. Fuel cells are used in space shuttles, where an electric current is produced by oxidizing hydrogen gas (the fuel) in an electrolyte cell.

fuel cell

Safety petrol container in a leak-resistant metal or plastic tank.
