| Abstract |
Microbial fuel cell (MFC) is a device that can produce electric energy from organic substances. The microbial biofilm on the anode surface converts organic substances into carbon dioxides, protons, and electrons. the most effective way for the anode enhancement is increasing anode surface because it is mainly affected by the amount of the electroactive bacteria on the anode surface. Meanwhile, the electrons from the anode are utilized for the reduction reaction on the cathode surface which is usually oxygen reduction reaction. Although platinum is known as the best material for this purpose, its high price and limited reserve have driven extensive research on alternatives to platinum. In this study, we report a photo-assisted MFC (PAMFC) in an attempt of enhancing power density in which p-type Cu2O was used as a cathode assistor. Upon illumination of visible light, we obtained power density of 1.4 W m-2 power density, that is 40% higher without light. |
