Dr Jon HerasDescriptionA diagram of the functioning of a hydrogen fuel cell, which recovers the maximum amount of chemical energy from hydrogen since it is not limited by the Carnot cycle.
Hydrogen enters the cell at the anode side, permeates the membrane and is catalytically split into positive hydrogen ions and electrons. The polymer electrolyte membrane allows the passage of hydrogen ions to the cathode, but electrons are forced to travel along an external circuit to the cathode, creating an electric current. At the cathode, the hydrogen ions, electrons and oxygen combine to produce water, the only waste product of the system.
