Behavior of copper in membrane

2017/3/29In membrane-less sediment microbial fuel cell (SMFC) reactors, copper ions are easily transported to the domains of both the anode and the cathode. Due to the unexpected balance between the biological effect of copper on the anode microbes and its function as electron acceptors at the cathode, the behavior of copper in membrane-less SMFCs became unexpected.

Recovery of Electrical Energy in Microbial Fuel Cells

2013/9/4Recovery of electrical energy is a key parameter for evaluating the performance of microbial fuel cells (MFCs). In this brief review, we analyze energy data in the sampled publications on continuously operated MFCs from the past 12 years and present a rough picture of energy recovery in MFCs. We observe that most MFCs produce a normalized energy recovery (NER) lower than 1.5
