摘要：

A microbial fuel cell using aerobic microorganisms as the cathodic catalysts is described. By using anaerobic sludge in the anode and aerobic sludge in the cathode as inocula, the microbial fuel cell could be started up after a short lag time of 9 days, generating a stable voltage of 0.324 V (Rex = 500 Ω). At an aeration rate of 300 ml min−1 in the cathode, a maximum volumetric power density of up to 24.7 W m−3 (117.2 A m−3) was reached. This research demonstrates an economic system for recovering electrical energy from organic compounds.
