▎ 摘　　要

NiWO4 and graphene oxide (NWG) modified anodic carbon cloth (CC) is used to improve the performance of single chambered microbial fuel cell (SMFC) by statistical optimization of operational parameters. The properties of synthesized NWG nanocomposite on the surface of modified anode are characterized by FTIR, XRD, EDX, TEM and SEM analysis. The optimum level of operational parameters maximize the power density (PD) 1458 mW/m(2) of SMFC having NWG modified anode and observed 8.5 fold improvements with respect to control. The electrochemical activities of the modified/un-modified anode in SMFC are determined by CV, PD, polarization curves and EIS. Significant improvement occurs in electron transfer between the microbes and modified anode due to internal resistance reduction and better biocompatible surface observed by EIS and microbial analysis results. The 10 miniaturize SMFCs in series, parallel and series-parallel connections produced 7, 31 and 18% higher PD in comparison with a medium size SMFC, respectively.
