ABSTRACT
This chapter discusses the basic principles of microbial fuel cell (MFC), various prototypes proposed for the conversion of waste materials either to fuel or energy, and their future prospects. It provides readers access to information in a simplified form for better understanding. A microbial fuel cell comprises a simple electrochemical setup whereby biocatalyst functions lead to reactions at the anode. The MFC setup is composed of minimal components usually possessing an anodic chamber containing microorganisms and wastewater, while an oxidant at the cathode is connected to an external circuit to generate electricity. A microbial electrolytic cell is a modified form of MFCs where the main motive is the conversion of organic matter into value-added products like hydrogen, methane, acetate, and hydrogen peroxide from which electricity can be produced indirectly. The collaborative analysis of biological and electrochemical influences will definitely help in the prediction of MFC output.
