Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
132 words
A METHOD FOR THE GENERATION OF ELECTRICAL ENERGY WHICH COMPRISES PROVIDING AN ELECTROCHEMICAL CELL CONTAINING AN AQUEOUS ALKALINE ELECTROLYTE BATH COMPRISING HYDROXYL ANIONS AND BARIUM CATIONS AND HAVING AN ANODE AND CATHODE DISPOSED THEREIN, SAID ANODE BEING IN CONTACT WITH A MATERIAL SELECTED FROM THE GROUP CONSISTING OF ELECMENTAL BARIUM IN THE SOLID STATE, A SOLID ALLOY BEING BARIUM AT LEAST 50 PERCENT BY WEIGHT OF THE ALLOY BEING BARIUM AND A LIQUID AMALGEN OF BARIUM, PASSING AN OXYGEN-CONTAINING GAS INTO SAID CELL SUCH THAT IT IS CONTACTED WITH SAID CATHODE, OPERATING THE CELL AT A TEMPERATURE BETWEEN ABOUT 20*C. AND THE ABOUT 250*C., BARIUM BEING CONVERTER ELECTROCHEMICALLY AT THE ANODE TO PRODUCE BARIUM CATIONS AND OXYGEN BEING CONVERTED ELECTROCHEMICALLY AT SAID CATHODE TO PRODUCE HYDROXYL ANIONS WITH GENERATION OF ELECTRICAL ENERGY.

Claim 3
Dependent Claim
166 words
A FUEL CELL FOR THE GENERATION OF ELECTRICAL ENERGY BY THE ELECTROCHEMICAL REACTION OF A SOLID FUEL AND A GASEOU OXIDANT WHICH COMPRISES IN COMBINATION A LIQUID ELECTROLYTE BATH HAVING VERTICALLY DISPOSED THEREIN A PLURALITY OF ANODES IN CONTACT WITH A SOLID FUEL AS THE ANODIC REACTANT AND A PLURALITY OF GAS DIFFUSION ELECTRODES IN ALTERNATING RELATIONSHIP TO SAID ANODES, THE ANODES AND CATHODES BEING SPACED APART FROM ONE ANOTHER AND HAVING LIQUID ELETROLYTE BATH BETWEEN THE OPPOSING REACTIVE ANODIC AND CATHODIC SURFACES, A MOVABLE CASING WITHIN WHICH THE ELECTROLYTE BATH IS CONTAINED AND TO WHICH THE ANODES AND CATHODES ARE CONNECTED, SAID CASNG BEING PROVIDED WITH MEANS FOR EFFECTUATING MOVEMENT THEREOF AND OF THE ANODES AND CATHODES WHICH ARE CONNECTED THERETO TOWARDS ONE ANOTHER AS THE SOLID FUEL IS CONVERTED BY THE ELECTROCHEMICAL CONVERSION THEREOF, MEANS FOR INTRODUCING A GASEOUS OXIDANT TO SAID GAS DIFFUSION CATHODES MEANS FOR INTRODUCING LIQUID ELECTROLYTE BATH TO THE CELL AND MEANS FOR WITHDRAWING LIQUID ELECTROLYTE BATH FROM THE CELL.
Claim 4
Dependent Claim
166 words
A FUEL CELL FOR THE GENERATION OF ELECTRICAL ENERGY BY THE ELECTROCHEMICAL REACTION OF A SOLID FUEL AND A GASEOU OXIDANT WHICH COMPRISES IN COMBINATION A LIQUID ELECTROLYTE BATH HAVING VERTICALLY DISPOSED THEREIN A PLURALITY OF ANODES IN CONTACT WITH A SOLID FUEL AS THE ANODIC REACTANT AND A PLURALITY OF GAS DIFFUSION ELECTRODES IN ALTERNATING RELATIONSHIP TO SAID ANODES, THE ANODES AND CATHODES BEING SPACED APART FROM ONE ANOTHER AND HAVING LIQUID ELETROLYTE BATH BETWEEN THE OPPOSING REACTIVE ANODIC AND CATHODIC SURFACES, A MOVABLE CASING WITHIN WHICH THE ELECTROLYTE BATH IS CONTAINED AND TO WHICH THE ANODES AND CATHODES ARE CONNECTED, SAID CASNG BEING PROVIDED WITH MEANS FOR EFFECTUATING MOVEMENT THEREOF AND OF THE ANODES AND CATHODES WHICH ARE CONNECTED THERETO TOWARDS ONE ANOTHER AS THE SOLID FUEL IS CONVERTED BY THE ELECTROCHEMICAL CONVERSION THEREOF, MEANS FOR INTRODUCING A GASEOUS OXIDANT TO SAID GAS DIFFUSION CATHODES MEANS FOR INTRODUCING LIQUID ELECTROLYTE BATH TO THE CELL AND MEANS FOR WITHDRAWING LIQUID ELECTROLYTE BATH FROM THE CELL.
Claim 5
Independent Claim
172 words
A METHOD FOR THE GENERATION OF ELECTRICAL ENERGY WHICH COMPRISES PROVIDING AN ELECTROCHEMICAL CELL CONTAINING AN AQUEOUS ELECTROLYTE BATH AND HAVING AT LEAST ONE ANODE AND AT LEAST ONE CATHODE DISPOSED THEREIN, SAID ANODE BEING IN CONTCT WITH A MATERIAL SELECTED FROM THE GROUP CONSISTING OF AN ALKALINE EARTH METAL IN ITS ELEMENTAL AND SOLID STATE, A SOLID ALLOY OF AN ELEMENTAL ALKALINE EARTH METAL AT LEAST 50 PERCENT BY WEIGHT OF THE ALLOY BEING AN ALKALINE EARTH METAL, AND A LIQUID AMALGAM OF AN ELEMENTAL ALKALINE EARTH METAL, PASSING AN OXIDANT COMPRISING HALOGEN INTO SAID CELL SUCH THAT IT IS BROUGHT INTO CONTACT WITH SAID CATHODE, THE AQUEOUS ELECTROLYTE BATH COMPRISING HALIDE ANIONS AND ALKALINE EARTH METAL CATIONS, OPERATING SAID CELL AT A TEMPERATURE BETWEEN ABOUT 20*C. AND ABOUT 250*C. SUCH THAT THE AQEUOUS ELECTROLYTE BATH IS MAINTAINED IN THE LIQUID PHASE, ALKALINE EARTH METAL REACTING AT THE ANODE TO PRODUCE CORRESPONDING ALKALINE EARTH METAL CATIONS AND HALOGEN REACTING AT THE CATHODE TO PRODUCE HALIDE ANIONS WITH GENERATION OF ELECTRICAL ENERGY.
