Being an exothermic redox reaction, electrical energy can be obtained directly from chemical energy if the two half reactions can be separated, with oxidation of hydrogen occurring at an anode and reduction of oxygen at a cathode. The fuel cell can operate with either an acid or an alkaline electrol ...
