Research Abstract

The goal of this study was to improve the MFCperformance (wastewater treatment and power generation) by enhanching the the cathode reaction of air-cathode MFC. To enhance the cathode reaction, we examined trhe effect of external proton supply by introducing the gas containing various concentrations of CO 2 and humidity to the cathode chamber. In addition, we could estimate quantitatively contribution of proton sources consumed by cathode reaction of air-cathode MFCs. Carbonate dissolution was a main proton source and water shortage was the most critical problem of cathode- reaction limitation. Finally, these results could suggest importance of adjustment of CO 2 content and humidity.
