Power Generation at Bulk Scale Operation of Microbial Fuel Cell

Abstract

Microbial fuel cells (MFCs) are an evolving technology for simultaneous bio-energy recovery and organic removal; however, the lack of studies conducted with largescale MFCs, obstructs further development of this technology. This paper presents experimental result of Bulk-scale microbial fuel cell (BSMFC) operation where, we have built and operated a 4.9 L microbial fuel. BSMFCs so developed works on parallel stacked arrangement of brush anode with series cathode chamber which calibrates the maximum power delivery power up to 1.6 V across the load. However, except for the first phase of the whole experimental operation maximum power density is not maintained steadily. Its electricity generation & performance was examined. Moreover, we identified important issues for the failed attempt to continuously generate high power when MFCs are enlarged.
