Claim 1
Independent Claim
142 words
AN ELECTROCHEMICAL PROCESS FOR GENERATING ELECTRICITY WHICH COMPRISES DISPOSING AN OXYGEN ELECTRODE AND A FUEL ELECTRODE IN SPACED RELATIONSHIP IN AN AQUEOUS ALKALINE ELECTROLYATE SOLUTION CONTAINING A REVERSIBLY-OXIDIZABLE POLYHDRIC PHENOL CONSISTING ESSENTIALLY OF A HYDROQUINONE, INTRODUCING FREE OXYGEN IN SAID ELECTROLYTE IN EFFECTIVE PROXIMITY TO SAID OXYGEN ELECTRODE, WHEREBY THE OXYGEN REACTS WITH SAID ELECTROLYTE TO FORM HYDROXYL IONS AND RELEASE ELECTRICAL CHARGES TO SAID OXYGEN ELECTRODE AND SAID POLYHYDRIC PHENOL IS OXIDIZED BY REACTING WITH HYDROXYL IONS IN SAID ELECTROLYTE TO FORM WATER AND RELEASE ELECTRICAL CHARGES TO SAID FUEL ELECTRODE, CONTACTING WITH SAID ELECTROLYTE A COMPOUND OF THE GROUP CONSISTING OF SODIUM HYDROSULFITE AND ETHYLENE, WHEREBY SAID COMPOUND IS OXIDIZED BY THE OXIDIZED FORM OF SAID POLYHYDRIC PHENOL AND THE OXIDIZED FORM OF SAID KPOLYHYDRIC PHENOL IS CONVERTED BACK TO THE REDUCED FORM, AND WITHDRAWING ELECTRICAL ENERGY FORM SAID ELECTRODES.
