The performance of a microbial fuel cell (MFC) was investigated at different temperatures and anodic media. A lag phase of 30 h occurred at 30 degrees C which was half that at room temperature (22 degrees C). The maximum power density at 30 degrees C was 70 mW/m(2) and at 22 degrees C was 43 mW/m(2). At 15 degrees C, no successful operation was observed even after several loadings for a long period of operation. Maximum power density of 320 mW/m(2) was obtained with wastewater medium containing phosphate buffer (conductivity: 11.8 mS/cm), which was approx. 4 times higher than the value without phosphate additions (2.89 mS/cm).
