A hydrogen fuel cell is a cell that uses a chemical element, hydrogen, and is manufactured to store energy. The basic principle is the reverse reaction of electrolyzed water, hydrogen and oxygen are supplied to the anode and cathode respectively, and after the hydrogen diffuses out through the anode and reacts with the electrolyte, electrons are released to reach the cathode through an external load.
