摘要

Microbial fuel cell (MFC), which can directly generate electricity from biodegradable materials, has been receiving increasing attention. Effects of temperature change on power density, electrode potential, columbic efficiency, chemical oxygen demand removal and internal resistance in two chambers MFCs were examined in this paper. The maximum power density of 7.89 W/m(3) was achieved at 37 degrees C, with 199% higher at 10 degrees C (2.64 W/m(3)), 24% higher at 30 degrees C (6.34 W/m(3)) and 21% higher at 43 degrees C, no steady power generation was observed at 55 degrees C. Low temperature to 10 degrees C might have a huge effect on anode potential, especially at higher current, but increasing the temperature to 43 degrees C had a main effect on the cathode performance when the MFCs have been established at 37 degrees C. The internal resistance of MFC was about 29 at 37 degrees C, and increased 62% and 303% when MFC switched to 30 degrees C and 10 degrees C. Similarly, internal resistance increased 48% at 43 degrees C. The effect of temperature on MFC performance was expressed by internal resistance, the higher the internal resistance of MFC, the lesser the power density obtained. The Columbic efficiencies were 8.65% at 30 degrees C, 8.53% at 37 degrees C, and 13.24% at 43 degrees C. These results demonstrate that MFCs can effectively be operated over a wide range of temperatures.
