摘要：A microbial fuel cell (MFC) with an algae-assisted cathode is a low-cost and sustainable way to provide the oxygen for the oxygen reduction reaction. The anode was with anaerobic microorganism, a kind of photosynthetic bacteria (PSB-B). An algae bioreactor was connected to cathode microbial fuel cells to increase power generation by supplying more oxygen to cathode electrode. In this study, we used red, blue and white LED light as the light source, and the anode and cathode were under irradiation respectively. The result showed that white LED light was an effective factor for the anode, the cell voltage was built up from 34 mv to 60 mv, power density increased up to 2.5 mW/m2, the red and blue light had positive impact on the voltage. At cathode, the voltage was almost on steady stage conditions, and it was fluctuated around 35 mv by oxygen bubbles that were produced by algae. This relatively simple method increased the oxygen reduction rate at a low cost and could be applied to improve the performance of MFC.
