  • Single chamber air cathode microbial fuel cells were assembled with iron instead of platinum as the cathode catalyst and ferrous carbon cloth as cathode. Impact of different iron content on electricity generation performance of MFC and long-run stability performance of iron-carbon air cathode MFC(Fe-C-ACMFC) with acetate as fuel were measured by steady discharging method and cyclic voltammetry. Results showed that with the increase of the iron content, the electricity generation performance of MFC was enhanced gradually, but decreased after achieving the peak value; when the iron content was 0.7 mg/cm2, the best performance of Fe-C-ACMFC was achieved with the maximum open circuit voltage of 593 mV, the apparent internal resistance of 89 Ω, and the maximum power density of 12 907 mW/m3. The discharge capacity of Fe-C-ACMFC with the iron content of 0.7 mg/cm2 was tested by cyclic voltammetry, showing that the long-run performance of Fe-C-ACMFC was stable.
