中文摘要：
本文采用过硫酸钾作阴极电子受体，阳极室接种厌氧活性污泥，构建了“H”型微生物燃料电池（MFC），并对电池产电性能进行了实验研究。结果表明，附着在阳极电极表面的生物膜对MFC的产电起着关键性的作用，电池性能随着阴极侧电解质溶液pH值降低而提高，随着过硫酸钾浓度增大而提高。电池的开路电压及最高输出功率在以过硫酸钾做电子受体时都要显著高于常用的铁氰酸钾电子受体。
英文摘要：
An H-type mierobial fuel cell （MFC） using potassium persulfate as cathodic electron acceptor was fabricated and successfully started up by inoculating anaerobic active sludge in anodic compartment. The electricity generation performances of the MFC under different conditions were investigated experimentally. The results show that the biofilms adhered to the surface of the anodic electrode made a dominating contribution to the electricity generation of the MFC. Furthermore, the MFC performance increased with decreasing pH value of the electrolyte solution and increasing potassium persulfate concentration in the cathodic compartment. The MFC with potassium persulfate as the cathodic electron acceptor achieved higher open-circuit voltage and maximum power density than that with hexacynoferrate.
