The study of mediator-less microbial fuel cell based on saccharomyces cerevisiae

To enhance power output and reduce cost for practical application of microbial fuel cell (MFC), extensive experiments have done to study performance optimization of lab-made mediator-less MFC. Saccharomyces cerevisiae was first tamed to investigate electrical adaptability as electricigens during device operation. By analyzing open circuit voltage using anodes with different materials, iron anode was proved to be the most suitable material for its highly electrochemical activity and bargain price. The results of experiment also proved that the performance of MFC could be reinforced through increasing roughness of anodes. Furthermore, electrical adaptability of electricigens would be enhanced after taming was confirmed.
