For the purpose of reducing the cost and improving the performance of cathodes in microbial fuel cells (MFCs), we prepared Pt/C and Pt-M/C (M = Ni, Co, Fe) electrodes, and characterized them by SEM, XRD and CV. The modified electrodes were used as the cathodes in double-chambered MFCs fed with synthetic medium and molasses sewage respectively. We have found that Pt-M/C catalysts had a better catalytic activity for oxygen reduction than Pt/C in the following order: Pt-Fe/C > Pt-Co/C > Pt-Ni/C > Pt/C. The maximum power density of the MFCs with Pt-M/C cathode was improved by 18-31% compared with the MFC with Pt/C cathode because of the decrease of activation loss in the cathode. This study shows that Pt-M/C catalysts can improve power generation of MFCs without affecting the COD removal and it is proposed that Pt-Fe functions best among the three Pt-M alloys as an efficient and cost-effective catalyst of MFCs.
