Sustainable power production in a membrane-less and mediator-less synthetic w…

Abstract. Microbial fuel cells (MFCs) fed with wastewater are currently considered a feasible strategy for production of renewable electricity. A membrane-less MFC with biological cathode was built from a compact wastewater treatment reactor and fed with synthetic wastewater. When operated with an external resistance of 250 W, the MFC produced a long-term power of about 70 mW/m2 for 10 months…
