Microbial fuel cell (MFC) is a new generation of energy technology. Electro Fenton Microbial Fuel Cell (EMFC) technology can effectively deal with sewage and provide electricity production function. The tungsten carbide and cobalt materials metallic crystalline material compared to traditional carbon substrate, which has good electrical conductivity and anti-corrosion. In this research, tungsten carbide anode coated with cobalt particle (2~5μm) was study. Experiments include electrochemical polarization characteristics, power density, corrosionTafel curve, contact angle measurement, metallographic cross-sectional observation and cathode RB5 dye decolorization and degradation analysis. The results show that in terms of electrical power system, 2μm cobalt strengthening electrode plate have the best electrical performance, the open circuit voltage of 0.60V, a maximum current density of 2,275.5mA/m2, the maximum power density of 323.5mW /m2. Tungsten carbide material after cobalt particle strengthening showing that the corrosion current decreased from 1.90 × 10-5A to 1.55 × 10-5A. This result indicates that cobalt particles strengthen tungsten carbide electrode plate in EMFC have the advantages of electric system elevation and corrosion rate decreasing.
