【摘要】 微生物燃料电池的出现使得降解有机污染物的同时收获电能成为可能,因而受到广泛关注。从产电微生物和电池结构两部分介绍了无介体微生物燃料电池的研究进展,对产电微生物的研究主要从产电微生物的种类、影响微生物产电的因素以及产电机理等方面进行阐述;对微生物燃料电池结构的研究,主要从电池阳极及阳极室、阴极及阴极室、分隔材料、整体结构和运行方式等方面进行了阐述;从提高微生物燃料电池产电能力的角度出发,对微生物和电池结构提出了研究方向,并展望了产电微生物燃料电池的研究前景。更多还原

【Abstract】 Microbial fuel cells(MFCs) are attracting wide attention because they make it possible to recover energy in the form of electricity from biodegradable compounds.This paper reviewed the progess in research of mediator-less MFCs including electricigens and the structure of MFCs.The electricigens including the main species,parameters affecting the electricity production and electron transfer mechanisms were described.The influences of the anode and anode chamber,the cathode and cathode chamber,the spreader,configuration and operation modes on MFC’s electricity production capacity were discussed.Some suggestions to enhance the power density of MFCs were offered.Also the vista for future research was prospected.更多还原
