| Abstract |
Microbial fuel cells (MFCs) are devices that use bacteria to generate electricity while simultaneously treating wastewater. Electrons produced by bacteria from organic matters are transferred to the anode and flow to the cathode through an external circuit in the MFCs. Currently, much research is underway to improve the performance of MFCs. We have tried to improve anode performance by using hematite, an n-type semiconductor. When the anode surface was coated with hematite and irradiated with visible light, both coulombic efficiency and power density were improved by 12.4% and 31.5%, respectively, compared to the dark operation. The effect of the semiconductor amount and other experimental conditions on the MFC performance is under examination. This preliminary result cast some hope of the real application of MFCs.
