Performance of a Microbial Fuel Cell using a Magnet Attached Cathode

摘要

Recently, a significant amount of attention has been focused on renewable energy sources that might help to satisfy increasing demand for energy consumption and environmental protection. From this perspective, microbial fuel cells (MFCs) are becoming an attractive prospect, owing primarily to their concurrent activities in wastewater treatment and electricity generation using wastewater as a fuel. An MFC is an electrochemical device which converts chemical energy to electrical energy using the catalytic activities of microorganisms. In recent years, significant effort has been expended toward the development of biological (i.e. bacteria and/or enzyme, etc) and non-biological components (i.e. electrochemical mediator, electrodes, membrane, MFC structure etc) for use in MFCs. Despite recent efforts to improve the electrical power performance of MFCs, there remain many technological barriers to overcome before the practical operation of a stable electrical power source becomes feasible.
