摘　　要：沉积物微生物燃料电池(sedimentmicrobialfuelcells,SM FC s),是一种基于沉积物环境体系,利用其中微生物的催化作用,将有机物中的化学能直接转变为电能的装置。首先介绍了SM FC s的工作原理,突出了微生物的作用。接着从电极本身和环境两方面综述了SM FC s的性能制约因素及改进措施,前者包括电极材料、电极设计、外加动力控制、外加电路控制等,后者包括有机物的供应、氧浓度、温度、电导率等。最后介绍了SM FC s在传感器供电方面的应用实例。Sediment microbial fuel cells（SMFCs） are devices that directly produce electricity from the oxidation of organic matter contained in the sediment through the catalytic reaction of microorganisms.In this paper,the operating principle of SMFCs firstly to emphasize the role of microorganisms was introduced.Subsequently,limiting factors for the power density of SMFCs as well as improvement programs were focused from two respects： electrodes and environment.The former included the material and design of electrodes,extra power plants,and external storage devices,and the latter contained the supply of organic substrates,the concentration of oxygen,temperature,and electric conductivity.Finally,some application examples of SMFCs as power source for sensors were presented.
