摘要

Microbial Fuel Cells (MFC) are capable of converting the chemical energy stored in the chemical compounds in a biomass to electrical energy with the aid of microorganisms. A better understanding of the relationship between the microbiological and electrical aspects of fuels cells is needed prior to successful MFC application. MFC constructed employing low-cost materials (salt bridge, graphite electrodes) without addition of any toxic mediators and using glucose (3 g L~(-1)) as substrate and three different electron acceptors potassium permanganate (KMnO_4), potassium ferricyanide (K_3[Fe(CN)_6]) and potassium dichromate (K_2Cr_2O_7) in the cathode chamber without pH adjustment was assessed in the present study. The results showed that MFC performance with KMnO_4 was superior than K_3[Fe(CN)_6] and K_2Cr_2O_7. Maximum voltage generation (OCV) and power density for KMnO_4 were 1.04 V and 7.29 mW m~(-2). Performance of MFC with K_3[Fe(CN)_6] and K_2Cr_2O_7 was much lower with a OCV and power density of 0.71 V; 0.92 mW m~(-2) and 0.56 V; 0.79 mW mm~(-2), respectively. Demonstrating that KMnO_4 can be used as an effective cathodic electron acceptor to enhance power output on MFC.
