Abstract: Microbial Electrolysis Cell (MEC)is a novel technology that treats wastewater usin
bacteria as catalyst and generates energy on the cathode simultaneously. In recent years, developing a
highly-efficient while low-cost cathode is very important for the application of MEC in wastewater
treatment. In this review, the regularly used cathodes and cathode catalysts including the precious metal
Pt, stainless steel, metal Ni, nano-materials, conductive polymers and composites as well as
biocathodes in MEC are summarized. The application of biocathodes in wastewater treatment and
energy generation is highlighted. Finally, the prospects of electrode development relating layout
optimization, composite materials synthesis and extracellular electron transfer mechanism are briefly
discussed. Stainless steel and nano-materials have good performanceand optimization of electrode
space layout and catalytic characteristics on electrode surface can strengthen the microbial adhesion
which ultimately promote the practical application of MEC.
