Microbial fuel cell(MFC) can directly convert chemical energy of organic substances to electric energy via the metabolic activity of microorganisms with the aid of a chemical redox mediator. Research on MFCs has been making great progress in terms of elevated power outputs as well as improved coulombic yields. MFC can exploit the whole biomass energy theoretically by far better than conventional biomass utilization technology, namely ethanol and methane fermentation because MFC requires neither any subsequent costly process such as distillation and distillate disposal like ethanol fermentation, nor reforming process for methane to hydrogen. With an alternative proton exchange membranes(PEM) to Nafion^[○!R], NeoSepta CMS was shown more durable and inexpensive as one of the essential components of MFC. In this study, we have applied organic wastewater, uncooked "raw" starch, and other unexploited biomass as a possible biofuel source for electricity generation.
