Abstract: Microbial fuel cell (MFC) was a tool for generating electrical currents via oxidizing organic compounds by using microorganisms as a biocatalyst. It was an effective approach to alleviate energy and environmental problems in the future，because it can convert chemical energy directly to electrical energy with biomass reactions，with higher energy conversion efficiency. This paper reviewed the new advances of electrogenesis microorganism species application，electrode materials and their modifications in MFC. The main developing directions and problems in this field were analyzed. The screening and mutagenesis of electrogenesis microorganisms to the tolerance of different organic substrates，the development of high efficiency and low price electrode materials and the construction of easy scale-up model of MFC were the focuses of research. The development of MFC should be focused on the scale-up of reactor in wastewater treatment，hydrogen production，electrochemical synthesis and biosensor，and determination of the operation parameters and models.
