Biochemical fuel cell

Claim 2

A PROCESS FOR OBTAINING ELECTRICAL POWER FROM BIOLOGICAL-BIOCHEMICAL PROCESSES WHICH PROCESS COMPRISES FORMING A FUEL CELL WHICH CONTAINS AN ANAEROBIC HALF-CELL HAVING THEREIN AN ANODE, AN ELECTRLYTE AND AN ELECTRICAL CONNECTION TO SAID DEVICE; IN SAID ANAEROBIC HALF-CELL ANAEROBICALLY EFFECTING, AT A PH OF ABOUT 6.0 TO ABOUT 8.0, THE OXIDATION OF A FUEL BY AN OXIDIZING MEDIUM COMPRISING AN OXIDATOR AND A HYDROGEN ACCEPTOR WHICH IS A REDOX INDICATOR DYE, ALLOWING ELECTRONS FROM SAID CONVERSION TO BE RELEASED TO SAID ANODE AND HENCE TO SAID DEVICE; REDUCING OXYGEN IN THE CATHODIC HALF-CELL; ALLOWING RESULTANT OXIDE IONS TO FLOW THROUGH SAID ELECTRLYTE TO SAID ANODE TO COMPLETE THE CIRCUIT; AND CIRCULATING SAID OXIDIZING MEDIUM TO A REJUVENATION CHAMBER IN WHICH IT IS EXPOSED TO OXYGEN PRIOR TO ITS RETURN TO SAID ANEROBIC HALF-CELL.

Claim 3

A PROCESS FOR OBTAINING ELECTRICAL POWER FROM BIOLOGICAL-BIOCHEMICAL PROCESSES WHICH PROCESS COMPRISES FORMING A FUEL CELL CONTAINING AN ANEROBIC HALF-CELL AND AN AEROBIC HALF-CELL EACH OF WHICH CONTAINS AN ELECTROLYTE AND AN ELECTRODE; ANAEROBICALLY EFFECTING, AT A PH OF ABOUT 6.0 TO ABOUT 8.0, THE OXIDATION OF A FUEL CONTAINING CARBON, HYDROGEN AND OXYGEN BY E. COLI WHICH FUNCTIONS AS AN OXIDATOR AND AS A HYDROGEN ACCEPTOR IN THE PRESENCE OF AN ANODE AND SAID ELECTRLYTE IN SAID ANAEROBIC HALF-CELL; ALLOWING ELECTRONS FROM THE SAID CONVERSION TO BE RELEASED TO THE SAID ANODE IN THE SAID ANAEROBIC HALF-CELL AND HENCE TO AN EXTERNAL CIRCUIT; REDUCING OXYGEN IN THE CATHODIC HALF-CELL OF SAID FUEL CELL AT A CATHODE CONTAINED IN SAID HALF-CELL AND CONNECTED TO SAID EXTERNAL CIRCUIT; AND ALLOWING THE RESULTANT OXIDE IONS TO FLOW THROUGH SAID ELECTROLYTES TO SAID ANODE TO COMPLETE THE CIRCUIT.

Claim 4

A PROCESS FOR OBTAINING ELECTRICAL POWER FROM BIOLOGICAL-BIOCHEMICAL PROCESSES WHICH PROCESS COMPRISES FORMING A FUEL CELL CONTAINING AN ANEROBIC HALF-CELL AND AN AEROBIC HALF-CELL EACH OF WHICH CONTAINS AN ELECTROLYTE AND AN ELECTRODE; ANAEROBICALLY EFFECTING, AT A PH OF ABOUT 6.0 TO ABOUT 8.0, THE OXIDATION OF A FUEL CONTAINING CARBON, HYDROGEN AND OXYGEN BY E. COLI WHICH FUNCTIONS AS AN OXIDATOR AND AS A HYDROGEN ACCEPTOR IN THE PRESENCE OF AN ANODE AND SAID ELECTRLYTE IN SAID ANAEROBIC HALF-CELL; ALLOWING ELECTRONS FROM THE SAID CONVERSION TO BE RELEASED TO THE SAID ANODE IN THE SAID ANAEROBIC HALF-CELL AND HENCE TO AN EXTERNAL CIRCUIT; REDUCING OXYGEN IN THE CATHODIC HALF-CELL OF SAID FUEL CELL AT A CATHODE CONTAINED IN SAID HALF-CELL AND CONNECTED TO SAID EXTERNAL CIRCUIT; AND ALLOWING THE RESULTANT OXIDE IONS TO FLOW THROUGH SAID ELECTROLYTES TO SAID ANODE TO COMPLETE THE CIRCUIT.
