Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
123 words
AN APPARATUS FOR ELECTROCHEMICALLY GENERATING ELECTRICITY COMPRISING A CELL VESSEL CONTAINING AN AQUEOUS ALKALINE ELECTROLYTE COMPARTMENT, AN OXYGEN ELECTRODE AND A FUEL ELECTRODE DISPOSED IN SPACED RE LATIONSHIP IN SAID ELECTROLYTE COMPARTMENT, SAID ELECTROLYTE COMPARTMENT BEING ADAPTED TO RECEIVE A SODIUM HYDROSULFITE FUEL AND CONTAINING OXIDIZING MEANS COMPRISING THE OXIDIZED FORM OF A POLYMER OF A POLYHYDRIC PHENOL SELECTED FROM THE GROUP CONSISTING OF HYDROQUINONE AND PYROGALLOL FOR OXIDIZING SAID FUEL UNDER CONDITIONS TO CONVERT THE OXIDIZED FORM OF SAID POLYMER TO THE REDUCED FORM, SAID POLYMER BEING INSOLUBLE IN SAID ELECTROLYTE AND ELECTRICALLY CONNECTED TO SAID FUEL ELECTRODE, MEANS FOR INTRODUCING FREE OXYGEN INTO ELECTROLYTE COMPARTMENTS IN EFFECTIVE PROXIMITY TO SAID OXYGEN ELECTRODE AND MEANS FOR WITHDRAWING ELECTRICAL ENERGY FROM SAID ELECTRODES.
Claim 2
Independent Claim

Claim 3
Dependent Claim
95 words
AN ELECTROCHEMICAL PROCESS FOR GENERATING ELECTRICITY COMPRISING DISPOSING AN OXYGEN AND A FUEL ELECTRODE IN SPACED RELATIONSHIP IN AN AQUEOUS ALKALINE ELECTROLYTE SOLUTION, DISPOSING IN SAID ELECTROLYTE AN ELECTROLYTEINSOLUBLE REVERSIBLY-OXIDIZABLE PYROGALLOL-FORMALDEHYDE POLYMER AND ELECTRICALLY CONNECTED TO SAID FUEL ELECTRODE, CONTACTING SAID ELECTROLYTE IN EFFECTIVE PROXIMITY TO SAID OXYGEN ELECTRODE WITH FREE OXYGEN, INTRODUCING IN SAID ELECTROLYTE IN EFFECTIVE PROXIMITY TO SAID POLYMER A SODIUM HYDROSULFITE FUEL OXIDIZABLE BY THE OXIDIZED FORM OF SAID POLYMER UNDER CONDITIONS TO CONVERT THE OXIDIZED FORM OF SAID POLYMER TO THE REDUCED FORM, AND WITHDRAWING ELECTRICAL ENERGY FROM SAID ELECTRODES.
