Fuel cells convert chemical energy into mechanical energy and into electrical energy. Battery cells convert chemical energy into electrical energy.

The key difference between a battery and a fuel cell is that a battery runs down as the electrodes dissolve, but a fuel cell operates for as long as oxygen and hydrogen flow. The battery is an energy storage device. It stores its fuel internally. A fuel cell is an energy conversion device. Its fuel is supplied externally.
