A biological fuel cell is a device that produces electrical energy by harnessing the oxidizing potential of anaerobic bacteria or enzyme. Biological fuel cell technology can potentially be applied in waste water treatment. Anaerobic microorganisms in a biological fuel cell oxidize various substrates and electron donors like sewage sludge and other carbon sources. Electrons that the anode accepts flow through a circuit to the cathode, where they are used in the reduction of oxygen (terminal electron acceptor) and convert protons to water. In this study, the most recent advances in biological fuel cell research emphases on applications in waste water treatment are summarized.
