Effect of Different External Resistance on Sedimentation Microbial Fuel Cells Performance

In this work, sediment microbial fuel cell (SMFC) with carbon cloth cathode, carbon plate anode and membranes based on ceramic materials was constructed in laboratory tests and various factors on SMFC power output were investigated. The state of the art on this topic has been comprehensively reviewed, and the effect of external resistance varying from 10.38MΩ on cell voltage, current and organic matter removal have been reported. The results obtained indicated that when external resistance was increased, the voltage decreased.
