Abstract

AbstractThe use of bacterial metabolism to oxidize organic matter and transfer electrons to the solid surface (electrode) leads to the development of microbial fuel cell (MFC) technology. Although MFCs have been utilized for biosensors, metals ion recovery, nutrient remediations, and synthesis of organic compounds; however, wastewater treatment and bioelectricity generation is the most generic application of MFC technology. The limitation in the commercialization of MFC is the lower power output and lack of efficient scale-ups. The MFC performance has been improved by optimizing the process parameters and various MFC reactor configurations with a focus on optimizing ohmic resistance, mass transport, and reaction kinetics. The vast research carried out on MFCs globally has led to various reactor designs. The vital components of MFC design include a group of separators, electrode materials, and reactor geometry. This chapter gives a detailed overview of conventional MFC configurations and current development in the innovative MFC designs for enhanced MFC performance and novel applications.KeywordsMicrobial fuel cellScale-upHigh-throughput systemWastewater treatmentBioelectricity
