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 (R (ex) = 500 Omega). 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.
描述了一种使用需氧微生物作为阴极催化剂的微生物燃料电池。通过使用阳极的厌氧污泥和阴极的好氧污泥作为接种物，该微生物燃料电池在9天的短暂延迟期后即可启动，产生稳定电压0.324 V（外电阻R = 500 Ω）。在阴极曝气速率为300 ml min⁻¹时，最大体积功率密度达到24.7 W m⁻³（117.2 A m⁻³）。本研究展示了一种从有机化合物中回收电能的经济系统。
