Insights into Microbial Fuel Cell: Recovering Energy from Microbial Electrolysis Cells for Low Power Applications

This paper examines the fundamentals, operational parameters, and applications of MFCs, in particular wastewater MFCs (WWMFCs), The WWMFCs were fed with the output effluent from a MEC (microbial electrolysis cell), coupling the system with a MEC (microbial electrolysis cell) which produces hydrogen and the MFCs which recover energy. Experimental data show a maximum power output of 600 µW from a single WWMFC at the maximum power point (MPP), highlighting their potential for powering low-energy devices while addressing environmental challenges.
