ABSTRACT:
A method of charging a metal-air or metal-oxygen electrochemical cell which serves to extend the useful life of the cell. Charging of the cell takes place with the addition of hydrogen to the air or oxygen cell which prevents the formation of oxygen and reduces the deterioration of the electrodes caused by oxidation. The conventional metal-air or metal-oxygen cell which is capable of injecting air or oxygen to the gas electrode during cell discharge is slightly modified to give it the ability to also inject hydrogen to the gas electrode during charging.
