Abstract:
1. A bio-fuel cell system for concurrent production of electrical power and single-cell protein, and consumption of carbon dioxide (CO 2 ), comprising; a cathode compartment containing a cathode electrode with an aqueous solution containing ferric ions (Fe an anode compartment containing an anode electrode; with a fuel having a hydrogen constituent being pumped directly into said anode compartment, said anode compartment being separated from said cathode compartment by a membrane permeable to protons, a reaction at the anode electrode being electrochemical oxidation of at least the hydrogen constituent of the fuel to produce electrons (e a bioreactor containing chemolithotrophic microorganisms and dissolved nutrients to facilitate growth of the chemolithotrophic microorganisms, a pump for pumping a fluid containing oxygen (O a pump for pumping a fluid containing said ferric ions (Fe wherein electrical power is obtained by making electrical connection between a load and the anode and cathode electrodes.
