Claim 1
Independent Claim
237 words
AN ELECTROCHEMICAL CELL FOR THE CONVERSION OF THE FREE ENERGY OF THE REACTION BETWEEN GASEOUS OXYGEN AND GASEOUS HYDROGEN DIRECTLY INTO ELECTRICITY COMPRISING A CELL CONTAINER, A PAIR OF GAS ELECTODES SPACED APART FROM EACH OTHER AND CONCENTRICALLY POSITIONED WITHIN SAID CONTAINER, MEANS POSITIONING SAID OUTER ELEC TRODE IN A SPACED RELATIONSHIP FROM SAID CONTAINER WALL WHICH MEANS SEALS THE SPACE BETWEEN SAID CONTAINER WALL AND SAID OUTER ELECTRODE AT BOTH ENDS OF SAID OUTER ELECTRODE, MEANS FOR INTRODUCING A GAS INTO THE SEALED SPACE BETWEEN SAID OUTER ELECTRODE AND SAID CELL CONTAINER, MEANS FOR SEALING THE ENDS OF THE INNER ELECTRODEM ENAS FOR INTRODUCING A GAS INTO THE CENTRAL PORTION OF SAID INNER ELECTRODE, BAFFLE MEANS EXTENDING UPWARD AT THE BOTTOM OF SAID CELL INTO SAID SPACE BETWEEN SAID OUTER ELECTRODE AND SAID CELL CONTAINER AND SPACED THEREFROM, AN ALKALINE ELECTROLYTE IN THE SPACE BETWEEN SAID CONCENTRICALLY POSITIONED ELECTRODES, THE SPACING BETWEEN SAID ELECTRODES BEING SUCH THAT THE INTERNAL RESISTANCE OF SAID CELL CAUSES INTERANL CELL HEATING WHICH CAUSES WATER IN THE ELECTROLYTE TO VAPORIZE INTO THE SAID SPACE BETWEEN SAID OUTER ELECTRODE AND SAID CONTAINER WALL AND TO CONDENSE ON THE INNER WALL OF SAID CELL CONTAINER, SAID WATER COLLECTING IN THE SPACES BETWEEN SAID CONTAINER WALL AND SAID BAFFLE MEANS AND BEING REMOVED FROM SAID CELL CONTAINER BY VENTING MEANS IN ASSOCIATION WITH THE SPACE BETWEEN SAID BAFFLE MEANS AND SAID CELL CONTAINER WALL.
