Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
49 words
A CARBONACEOUS FUEL REFORMER COMPRISING AN ENCLOSED CONTAINER HAVING A PLURALITY OF FORAMINOUS BAFFLES SUPPORTED THEREIN, MEANS FOR INTRODUCING A MIXTURE COMPRISING H2O AND CARBONACEOUS FUEL INTO SAID CONTAINER, A LIQUID INORGANIC SALT SUPPORTED WITHIN THE FORMAMINA OF SAID BAFFELS, AND MEANS FOR REMOVING FORMED FUEL FROM SAID CONTAINER.
Claim 2
Dependent Claim
49 words
A CARBONACEOUS FUEL REFORMER COMPRISING AN ENCLOSED CONTAINER HAVING A PLURALITY OF FORAMINOUS BAFFLES SUPPORTED THEREIN, MEANS FOR INTRODUCING A MIXTURE COMPRISING H2O AND CARBONACEOUS FUEL INTO SAID CONTAINER, A LIQUID INORGANIC SALT SUPPORTED WITHIN THE FORMAMINA OF SAID BAFFELS, AND MEANS FOR REMOVING FORMED FUEL FROM SAID CONTAINER.
Claim 3
Independent Claim
128 words
AN APPARATUS FOR CONVERTING CARBONACEOUS FUEL TO ELECTRICAL ENERGY COMPRISING (A) A FUEL CELL, (B) A CARBONACEOUS FUEL REFORMER, SAID CARBONACEOUS FUEL REFORMER COMPRISING AN ENCLOSED CONTAINER PARTIALLY FILLED WITH SULFATES OR CARBONATES OF SODIUM, LITHIUM OR POTASSIUM OR MIXTURES THEREOF AND HAVING A PLURALITY OF FORAMINOUS BAFFES THEREIN, SAID BAFFLES BEING COMPRISED OF NICKEL, NICKEL ALLOYS, OR CHROME STEEL AND SUPPORTING SAID SULFATES OR CARBONATES WITHIN THE FORAMINA THEREOF, SAID BAFFLES BEING POSITIONED BETWEEN THE INLET AND OUTLET OF SAID FUEL REFORMER, (C) MEANS FOR MIXING H2O PRODUCED BY SAID FUEL CELL WITH SAID CARBONACEOUS FUEL AND INTRODUCING THE MIXTURE INTO SAID INLET OF SAID CARBONACEOUS FUEL REFROMER, AND (D) MEANS FOR WITHDRAWING IMPURE HYDROGEN FROM SAID REFORMER AND INTRODUCING SAID IMPURE HYDROGEN INTO SAID FUEL CELL.
Claim 4
Independent Claim
128 words
AN APPARATUS FOR CONVERTING CARBONACEOUS FUEL TO ELECTRICAL ENERGY COMPRISING (A) A FUEL CELL, (B) A CARBONACEOUS FUEL REFORMER, SAID CARBONACEOUS FUEL REFORMER COMPRISING AN ENCLOSED CONTAINER PARTIALLY FILLED WITH SULFATES OR CARBONATES OF SODIUM, LITHIUM OR POTASSIUM OR MIXTURES THEREOF AND HAVING A PLURALITY OF FORAMINOUS BAFFES THEREIN, SAID BAFFLES BEING COMPRISED OF NICKEL, NICKEL ALLOYS, OR CHROME STEEL AND SUPPORTING SAID SULFATES OR CARBONATES WITHIN THE FORAMINA THEREOF, SAID BAFFLES BEING POSITIONED BETWEEN THE INLET AND OUTLET OF SAID FUEL REFORMER, (C) MEANS FOR MIXING H2O PRODUCED BY SAID FUEL CELL WITH SAID CARBONACEOUS FUEL AND INTRODUCING THE MIXTURE INTO SAID INLET OF SAID CARBONACEOUS FUEL REFROMER, AND (D) MEANS FOR WITHDRAWING IMPURE HYDROGEN FROM SAID REFORMER AND INTRODUCING SAID IMPURE HYDROGEN INTO SAID FUEL CELL.
Claim 5
Independent Claim
53 words
THE METHOD OF REFORMING HYDROCARBON FUEL TO IMPURE HYDROGEN COMPRISING THE STEPS OF (A) MIXING SAID HYDROCARBON FUEL WITH H2O, AND (B) PASSING THE MIXTURE OF HYDROCARBON FUEL AND H2O THROUGH FORAMINOUS CATALYST PLATES HAVING CARBONATES OR SULFATES OF LITHIUM, SODIUM, OR POTASSIUM OR MIXTURES THEREOF WITHIN THE FORAMINA OF SAID CATALYST PLATES.
Claim 6
Independent Claim
53 words
THE METHOD OF REFORMING HYDROCARBON FUEL TO IMPURE HYDROGEN COMPRISING THE STEPS OF (A) MIXING SAID HYDROCARBON FUEL WITH H2O, AND (B) PASSING THE MIXTURE OF HYDROCARBON FUEL AND H2O THROUGH FORAMINOUS CATALYST PLATES HAVING CARBONATES OR SULFATES OF LITHIUM, SODIUM, OR POTASSIUM OR MIXTURES THEREOF WITHIN THE FORAMINA OF SAID CATALYST PLATES.
Claim 7
Independent Claim
120 words
THE METHOD OF CONVERTING CARBONACEOUS FUEL TO ELECTRICAL ENERGY WHEREIN IMPURE HYDROGEN IS FED INTO THE FUEL SIDE OF A FUEL CELL AND AIR IS FED INTO THE OXIDANT SIDE OF SAID FUEL CELL, THEREBY PRODUCING ELECTRICAL ENERGY, CO2 AND H2O, COMPRISING THE STEPS OF (A) MIXING SAID H2O PROCUCED BY SAID FUEL CELL WITH A CARBONACEOUS FUEL, (B) PASSING THE MIXTURE OF H2O AD CARBONACEOUS FUEL THROUGH A FORAMINOUS CATALYST HAVING A COATING OF INORGANIC SALT THEREON, (C) MAINTAINING SAID FORAMINOUS CATALYST AT A TEMPERATURE BETWEEN ABOUT 350*C. AND ABOUT 750*C., THEREBY REFORMING SAID CARBONACEOUS FUEL TO IMPURE HYDROGEN AND CARBON DIOXIDE, AND (D) FEEDING SAID IMPURE HYDROGEN AND CARBON DIOXIDE INTO SAID FUEL SIDE OF SAID FUEL CELL,
Claim 8
Independent Claim
120 words
THE METHOD OF CONVERTING CARBONACEOUS FUEL TO ELECTRICAL ENERGY WHEREIN IMPURE HYDROGEN IS FED INTO THE FUEL SIDE OF A FUEL CELL AND AIR IS FED INTO THE OXIDANT SIDE OF SAID FUEL CELL, THEREBY PRODUCING ELECTRICAL ENERGY, CO2 AND H2O, COMPRISING THE STEPS OF (A) MIXING SAID H2O PROCUCED BY SAID FUEL CELL WITH A CARBONACEOUS FUEL, (B) PASSING THE MIXTURE OF H2O AD CARBONACEOUS FUEL THROUGH A FORAMINOUS CATALYST HAVING A COATING OF INORGANIC SALT THEREON, (C) MAINTAINING SAID FORAMINOUS CATALYST AT A TEMPERATURE BETWEEN ABOUT 350*C. AND ABOUT 750*C., THEREBY REFORMING SAID CARBONACEOUS FUEL TO IMPURE HYDROGEN AND CARBON DIOXIDE, AND (D) FEEDING SAID IMPURE HYDROGEN AND CARBON DIOXIDE INTO SAID FUEL SIDE OF SAID FUEL CELL,
