The microbial fuel cell (MFC) is a promising bio-electrochemical system, which can directly convert the organic chemical energy into the electrical energy with microbes as the catalyst to degrade the organic sewage and produce electricity at the same time. This paper presents a comprehensive review of the latest studies of electrode materials, including the modification and the functionalization of anode materials, and of the cathode catalyst. Additionally, the direction of the electrode design and research in the MFC is suggested.
