The air depolarized cell comprises a laminated cathode assembly including an air cathode and an auxiliary cathode in combination with a layer of a thin film nonporous gas permeable membrane which is disposed with one side over the air cathode and with the opposite side having substantially unrestricted access to the atmosphere through a gas diffusion member. The nonporous membrane controls the transfer of oxygen from the ambient atmosphere to the air cathode exclusively by gas solubility with its permeability to oxygen selected to correspond to a predetermined average current density for the cell. |
