In order to confirm the effects of the low conductivity and biodegradability of wastewater, flat-panel aircathodemicrobial fuel cells (FA-MFCs) were operated by supplying substrates with different volumeratios of domestic wastewater mixed with an artificial medium: the artificial medium only, 25% wastewater,50% wastewater, 75% wastewater, 100% of wastewater with 500 mg-COD/L by adding acetate, andraw domestic wastewater (230 mg-COD/L). With the increase of wastewater ratio, the maximum powerdensity and organic removal efficiency decreased from 187 to 60 W/m3 and 51.5 to 37.4%, respectively,but the Coulombic efficiency was maintained in the range of 18.0?18.9%. The FA-MFCs could maintaintheir low internal resistances and overcome the decreasing conductivity. The acetate concentrationwas more important than the total organics for power production. This study suggests that the FAMFCconfiguration has great applicability for practical applications when supplied by domestic wastewaterwith low conductivity and biodegradability.
