The SCBFC was composed of bilayered cathode,the outside of which was modified with Fe3+ (graphite-Fe(III)cathode) and the inside of which was porcelain membrane,and of an anode which was modified with Mn4+ (graphite-Mn(IV) anode). The graphite-Fe(II), graphite-Mn(IV), andporcelain membrane were designed to have micropores. Theoutside of the cathode was exposed to the atmosphere and theinside was contacted with porcelain membrane. In all SCBFCSthe graphite-Fe(III) was used as a cathode, and graphite-Mn(IV)and normal graphite were used as anodes, for comparison ofthe function between normal graphite and graphite-Mn(IV)anode. The potential difference between graphite-Mn(IV) anodeand graphite-Fe(III) cathode was about 0.3 volt, which is thesource for the electron driving force from anode to cathode. Inchemical fuel cells composed of the graphite-Mn(IV) anodeand graphite-Fe(III) cathode, a current of maximal 13 mA wasproduced coupled to oxidation of NADH to NAD+ the currentwas not produced in SCBFC with normal graphite anode.When growing and resting cells of E. coli were applied to theSCBFC with graphite-Mn(IV) anode, the electricity productionand substrate consumption were 6 to 7 times higher than inthe SCBFC with normal graphite anode, and when we appliedanaerobic sewage sludge to SCBFC with graphite-Mn(IV)anode, the electricity production and substrate consumptionwere 3 to 5 times higher than in the SCBFC with normalgraphite anode. These results suggest that useful electric energymight possibly be produced from SCBFC without electronmediators, electrode-active bacteria, and extra energy consumption for the aeration of catholyte, but with wastewater as a fuel.
