Abstract: A TWO-ELECTRODE RECHARGEABLE METAL/AIR OR METAL/OXY GEN DEPOLARIZED ELECTROCHEMICAL CELL AND METHOD OF GENERATING ELECRICITY THEREFROM ARE DESCRIBED. THE ELECTROCHEMICAL CELL COMPRISES AN ANODE CAPABLE OF BEING REGENERATED, A COMPOSITE CATHODE HAVING AN OXYGEN PERMEABLE HYDROPHOBIC MEMBER LAYERED WITH CATALYST, AND A CURRENT COLLECTOR IN CONTACT WITH THE LAYERED CATALYST ON SAID MEMBER. THE CATHODE IS CONSTRUCTED AND ARRANGED IN ORDER THAT THE CURRENT COLLECTOR IS IN REMOVABLE ELECTRICAL CONTACT WITH THE CATALYST. THUS, FOR CELL DISCHARGE, THE CURRENT COLLECTOR CONTACTS THE CATALYST AND TRANSPORTS ELECTRONS TO THE EXTERNAL CIRCUIT. FOR CELL RECHARGE, THE CURRENT COLLECTOR IS ELECTRICALLY SEPARATED FROM THE CATALYST WHEREBY NUMEROUS DISCHARGE-RECHARGE CYCLES OF THE CELL MAY BE EFFECTED WITHOUT DAMAGE TO THE CATHODE.
