A microbial fuel cell MFC with an algae-assisted cathode is a low-costand sustainable way to provide the oxygen for the oxygen reduction reaction.The anode was with anaerobic microorganism, a kind of photosyntheticbacteria PSB-B. An algae bioreactor was connected to cathode microbial fuelcells to increase power generation by supplying more oxygen to cathodeelectrode. In this study, we used red, blue and white LED light as the lightsource, and the anode and cathode were under irradiation respectively. Theresult showed that white LED light was an effective factor for the anode, thecell voltage was built up from 34 mv to 60 mv, power density increased up to2.5 mW-m2, the red and blue light had positive impact onthe voltage. At cathode, the voltage was almost on steady stage conditions, andit was fluctuated around 35 mv by oxygen bubbles that were produced by algae. Thisrelatively simple method increased the oxygen reduction rate at a low cost and couldbe applied to improve the performance of MFC.
