cell that produces electricity by oxidation of fuel (hydrogen and oxygen or zinc and air); often used in electric cars

a cell that converts solar energy into electrical energy

a cell that can be recharged

an electric cell that generates an electromotive force by an irreversible conversion of chemical to electrical energy; cannot be recharged
