| Abstract |
Metal complex-microbial fuel cells (MFCs) have been investigated in this work with intent manufacturing high performance MFC batteries. The performance of metal complex MFCs was evaluated by polarization and discharge experiments using a battery consisting of 3 MFC unit cells. The results indicated that the performance of the [Fe(III)(4,4’-dimethyl-2,2’-bipy)3]-MFC was much better than the other MFCs containing Cr(VI) or Fe(III) as an electron acceptor. At a discharging current of 3 mA (2 A/m2), the average discharging potential was found to be 0.927 V under a parallel-connection, sustaining more than 20 hours with an open circuit voltage of 1.210 V. Fe(III)(4,4’-dimethyl-2,2’-bipyridyl)3-MFC showed much higher electrochemical parameters than Cr(VI)-MFC and Fe(III)-MFC. Highest maximum power of 3937 mW/m2 could be obtained from the battery consisting of 3 MFCs in parallel. |
