Research progress of electrode materials for microbial fuel cells

Microbial fuel cell(MFC) is a new technology that simultaneously treats wastewater and converts its chemical energy into electrical energy using bacteria as catalyst.Research progress of anode/cathode materials and catalysts for MFCs were reviewed.Methods of improving MFCs performance were discussed,such as using nano-materials to improve the surface area of electrodes,making composite materials to combine the advantages of different materials to overcome the shortage of single materials.Prospects of faster commercial use of MFCs were discussed,for example,coupling with other techniques.
