Abstract
Bioelectrochemical system (BES) has made significant advancement in last decade indifferent modes for converting organic waste material into bioelectricity. In this chapter, we review the basic aspects of a microbial fuel cell (MFC) that produces bioelectricity through the biodegradation of organic waste present in wastewaters and study the influencing factors such as membranes in MFC, electrodes, pH and temperature. A classic MFC subsists of cathode and anode electrode chambers separated by a cation or anion exchange membrane. Various substrates such as synthetic wastewater, municipal wastewater, biowaste, and industrial wastewater rich in organic content can be treated in MFC for removal of organic content with bioelectricity generation simultaneously. In this chapter, the effect of various substrate (biowaste) and configuration on the MFC performance on bioelectricity generation is presented. Also, this chapter demonstrates the improvements made in MFCs in recent years with summarization of their advantages and possible future applications. Different key influencing factors affecting bioelectricity generation on MFCs are elaborated, and these key parameters are fully discussed.
