This paper focuses on the long term operation and testing of three Microbial Fuel Cells (MFC) having three different anode materials: commercial carbon felt (C-FELT), polyaniline-deposited carbon felt (C-PANI) and carbon-coated Berl saddles (C-SADDLES). A mixed consortium from seawater was used as inoculum and acetate was used as substrate. Tests were conducted for four months under 1000 X external load. The maximum power generation was obtained by C-SADDLES (102 mWm2) followed by C-FELT and C-PANI, respectively. A similar trend was obtained with the evaluation of electrical energy produced: C-SADDLES (2222 J), C-PANI (2183 J) and C-FELT (2114 J). However, the performance of C-PANI decreased over time, most evidently due to degradation or deactivation of deposited polyaniline by the microorganisms’ activity. These results provide evidence that the three-dimensional structure, C-SADDLES, offers excellent biocompatibility, high specific surface area, high conductivity and most importantly these properties are maintained for a long period of time.
