The hydrogen-oxygen fuel cell is described in Section 18.6
Hydrogen-Oxygen fuel cell works on the principle of oxidation of hydrogen and reduction of oxygen, it was made up of potassium hydroxide as an electrolyte solution and two inert electrodes. Hydrogen and oxygen gases were bubbled through the anode and cathode compartments. The cell reaction of hydrogen-oxygen fuel cell was shown below.
