Microbial fuel cells (MFC), which convert chemical energy of organic compounds to electric energy, have developed in recent years. MFCs may play an important role in sewage plants, where organic compounds in sewage are removed by microbes. We examined three kinds of sewage, i.e. inflow sewage that flowed into the plant, precipitation sewage, which was obtained by removing solid particles by precipitation from the former, and activated sludge, which was mixed with microbes and incubated to remove organic compounds. We observed the maximum electric power, 0.33 gW/cm2, in the inflow sewage. The output of the MFC depended on the kind of the sewage and stored time of the sewage. It was suggested that some microbes in the sewage enhanced the performance of the MFC.
