ABSTRACT:
Disclosed are methods of operation for oxygen electrodes which maximize the power efficiency available from such oxygen electrodes while minimizing the voltage necessary to operate such oxygen electrodes. These methods include control of the pressure of the air feed side of the oxygen electrode, control of the total flow of the air feed side, the humidification of the air feed side of the oxygen electrode and the elimination of CO.sub.2 from the air feed to the oxygen electrode to increase the lifetime of such electrodes as applied to a chlor-alkali electrolytic cell.
