Abstract
The Microbial Fuel Cell (MFC) is a bioreactor with which the chemical energy in chemical bonds of organic compounds are converted to electricity under anaerobic conditions through catalytic reactions of micro-organisms. It has been familiar for a long time that electricity can be generated directly through using bacteria to break organic matter. A microbial fuel cell can also serve in different wastewater treatment to destroy organic matter. The development of MFC technology requires a greater understanding of the microbial processes for MFCs, and their components, limitations, factors and design this system, to be simpler and large scale system developed; so that it would increase electricity production while being cost-effective. This review discusses, what is the MFCs and the basic principle of how MFC operate, the most essential MFC components and their relevance, multiple MFC designs that have been presented as efficient configurations, Applications of MFCs, and several types of wastewater as substrates in MFC also highlighted.

This paper aims to review on use of different wastewaters in Microbial Fuel Cell (MFC), the current knowledge of microbiology in the production of electrical power, as substrates in MFC the methods and materials used to construct this technology, and the applications of MFC
Double-Chamber MFCs: Two-chambered MFCs is a typical and preferred MFC design, which mainly consist of an anode and cathode compartment separated proton exchange membrane (PEM) or by a salt bridge, through which the protons move toward the cathode ]24[
Summary
One of the most important challenges facing the world at the present time is energy problems due to the depletion of energy sources represented by fossil fuels and global warming. MFC is new and promising technology through which electricity is produced during pollutants are removed from wastewater[2]. MFC is an electrochemical biological system that works to convert the potential energy contained within the bounds of organic matter that is degradable by microorganisms into clean electrical energy. This paper aims to review on use of different wastewaters in MFC, the current knowledge of microbiology in the production of electrical power, as substrates in MFC the methods and materials used to construct this technology, and the applications of MFC
