Electrode Material as Anode for Improving the Electrochemical Performance of Microbial Fuel Cells

Abstract

The energy generation without causing environmental pollution is a unique idea to make a better survival for human beings. In this regard, microbial fuel cells (MFCs) have been considered to be eco-friendly and efficient technology to produce renewable energy. The operations and functioning of MFCs technology were affected by many factors but the electrodes are the most essential and significant aspects in MFCs. Moreover, a wide variety of electrodes and MFCs configurations have been developed to enhance the electrochemical performance of MFCs. The carbon materials (graphite, graphene etc.) were commonly used for the electrode fabrication, due to some unique properties such as high conductivity, good thermal stability, high surface area, good mechanical power etc. In this chapter, different electrode materials, used for anode fabrication were summarized to reveal the performance/efficiency toward the generation of electricity. Finally, the electrochemical characterizations tool, current challenges, and future perspectives of the electrode in MFCs were discussed briefly.
