Abstract: Microbial fuel cell (MFC) is a technology that can harvest the chemical energy of an organic fuel directly into the form of electricity by using microorganisms growing on its anode. MFC demonstrates great potential in supplying electrical power to sustain a wastewater treatment plant. In this study, various MFC reactor configurations have been designed to seek the maximum power production with the minimum cost. The impacts of the types of catholyte, proton exchange membrane (PEM) and anode materials were tested. Scrap metal alloys recycled from industrial activities (electronics, automobiles, etc.) were also used as cathode catalysts to replace the expensive platinum catalyst. The results show that Inconel had the highest power production to cost ratio with long term stability as a cathode catalyst. When operated in a full loop mode where the anodic effluent was directly injected into the cathode in an up-flow manner, increased organic removal was achieved with the highest maximum power produced.
