Abstract:

A dual-chamber microbial fuel cell(MFC) which used phenol as the fuel, biofilm electrode as the negative electrode, Ti/SnO2-Sb2O5/PbO2 electrode as the positive electrode was set up. The biofilm electrodes were prepared by micro-current culture and natural culture methods, respectively. Effects of the microbial culture methods, biofilm formation time and substrate materials on the electricity generation ability of the MFC were investigated. The experimental results showed that the micro-current culture method was better than natural culture method, the biofilm electrodes which were prepared by micro-current culture method had higher electricity generation ability than those prepared by natural culture method. When the biofilm formation time was 8 d, the MFC had the best electricity generation ability, and its maximum power density was 39 mW/m2. The order of the substrate materials of which the MFC with higher to lower electricity generation ability was carbon felt>graphite>titanium mesh>foam titanium.

Key words: Biofilm electrode, Microbial fuel cell(MFC), Phenol, Ti/SnO2-Sb2O5/PbO2 electrode, Substrate material
