The paper involved two parts: Part 1: A two-chambered microbial fuel cell was constructed with high-concentration sodium acetate as fuel in the anode. The influence of different electron acceptors in the cathode, external resistance value, pH value and concentration of sodium acetate on electricity generation in MFC was investigated. The result showed that the maximum power density of 294.72 mW/m2 and the coulombic efficiency of 25.87% was achieved at sodium acetate concentration of 6.46 g/L, pH 7.0, external resistance 500Ωin the anode and when using potassium permanganate as electron acceptor in the cathode.

The results show that:(1) MnO2 deposition on the surface is the main factor resulting in cathode polarization, and the flowing of the solution can remarkably reduce this polarization. Furthermore, the buffered solution can reduce the polarization resulting from H+ concentration difference;(2) it is deduced from the polarization curve that the key factor influencing the performance of MFC is microbial number and metabolic rate and the electron transferring rate from microbial to electrode;(3) the power density arrives at the biggest, 824 mW/m2, when outer resistance is 300 Ω, which is accordance to the inner resistance,(284±18)Ω, deduced from I-V curve;(4) the influences of pH and permanganate concentration on cathode potential is in agreement to Nernst equation.
