Abstract

A fabrication method of cathode in a direct microbial fuel cell was studied, and the primary influential factors of fabrication were investigated. The performances of cathodes obtained at different fabricating conditions were evaluated by the power density and voltage-current curves. The results showed that they were much affected by the concentration of PTFE in the impermeable layer, Nafion content in the catalyst layer and carbon content in the flattening layer. When the concentration of PTFE was 30%(ω), Nafion content 2.8 mL, and carbon content 0.18 g, the best performance was obtained. The power density output was 357 mW/m², and the COD removal rate reached 90%.
