Abstract

A metal-air electrochemical cell comprising an oxygen reservoir disposed in an air plenum adjacent the air cathode. The oxygen reservoir includes an oxygen binding compound characterized in that the oxygen binding compound reversibly binds oxygen and releases oxygen into the air in the air plenum to power the cell when the partial pressure of oxygen in the air plenum drops due to a load on the cell.
