POSSIBILITY OF USING SEDIMENT MICROBIAL FUEL CELLS FOR DECARBOBUZATION

Abstract

 Sediment Microbial Fuel Cells (SMFC) is a device that converts the reduced enrgy of sediment into electric power. SS-SMFC, which is a mixure of steel slag (SS) and sediment, has high power generation capacity. On the other hand, SS-SMFC has not been put into practical use because the current processing capacity of the cathode is the rate-determing factor and the internal resistance is lager than that of general cells. The purpose of this study is to construct a practical power generation spscification for SS-SMFC. We investigated an energization method to reduce the cathode overvoltage, then succeeded in developing an air cathode with an improved cathode oxygen supply rate, and experimentally determined the external resistance and cathode-anode ratio that maximize the power density, and SS-SMFC.
