Abstract

The microbial fuel cell (MFC) has attracted research attention as a biotechnology capable of converting hydrocarbon into electricity production by using metal reducing bacteria as a biocatalyst. Electricity generation using a microbial fuel cell (MFC) was investigated with acetate as the fuel and Geobacter sulfurreducens as the biocatalyst on the anode electrode. Stable current production of 0.20-0.24 mA was obtained at 30-32 °C. The maximum power density of 418-470 mW/m2, obtained at an external resistor of 1,000 Ω, was increased over 2-fold (from 418 to 866 mW/m2) as the Pt loading on the cathode electrode was increased from 0.5 to 3.0 mg Pt/cm2. The optimal batch mode temperature was between 30 and 32 °C with a maximum power density of 418-470 mW/m2. The optimal temperature and Pt loading for MFC were determined in this study. Our results demonstrate that the cathode reaction related through the Pt loading on the cathode electrode is a bottleneck for the MFC's performance.
