Microbial fuel cells (MFCs) are capable of processing wastewater and producing electricity simultaneously. To date, the main challenge has been to obtain sufficient power density and to establish the optimal volume. However, the maximum voltage will never exceed the theoretical open circuit voltage. Anode materials and their structures are key factors in the successful performance of MFCs. Liquid-solid fluidized bed was combined with a single-chamber air cathode MFC reactor, constructing an anaerobic fluidized bed microbial fuel cell (AFBMFC). Polyacrylonitrile / multi-walled carbon nanotube composite film anodes were prepared in cyclic voltammetry method and applied to AFBMFC. The surface structure, electrochemical properties, and prepared electrodes were investigated. The output voltage, power density and efficiency of sewage treatment for MFC were evaluated.
