ABSTRACT:
Metal/oxygen cells such as zinc/air cells are provided with optimum active life characteristics by interposing, on the air side of the cell, an oxygen diffusivity-limiting membrane, such as, for example, sintered polytetrafluoroethylene, so that no more oxygen is received than is needed for the current rate required for the intended application.
