A microbial fuel cell (MFC) is a bioreactor that converts chemical energy in the chemical bondsin organic compounds to electrical energy through catalytic reactions of micro-organisms underanaerobic conditions. It has been known for many years that it is possible to generate electricitydirectly by using bacteria to break down organic substrates. Due to the promise of sustainableenergy production from organic wastes, research has intensified in this field in the last few years.While holding great promise only a few marine sediment MFCs have been used practically,providing current for low power devices. To further improve MFC technology an understandingof the limitations and microbiology of these systems is required. The aim of this paper is areview study on MFC technology and its applications.
