Abstract

A bifunctional air-electrode for use in electrochemical energy cells discharges a satisfactory current on the first discharge cycle and operates for a relatively large number of charge-discharge cycles without gas forming between the electrolyte side of the air electrode and the electrolyte. The active layer of the electrode includes an oxygen reduction catalyst having a first oxygen evolution potential and an oxygen evolution catalyst having a second oxygen evolution potential less than the first oxygen evolution potential, the oxygen reduction catalyst being present in a greater concentration proximate the electrolyte side than proximate the air side and the oxygen evolution catalyst being present in a greater concentration proximate the air side than proximate the electrolyte side.
