Abstract: One type of genuine fuel cell that does hold promise in the long-term is the biological fuel cell.Un ike conven-tional fuel cells, which employ hydrogen, ethanol and methanol as fuel, biological fuel cells use organic pro-ducts produced by metabolic processes or use organic electron donors utilized in the growth processes as fu-els for current generation. A distinctive feature of bio-logical fuel cells is that the electrode reactions are controlled by biocatalysts, i.e. the biological redox-reactions are enzymatically driven, while in chemical fuel cells catalysts such as platinum determine the electrode kinetics. This article provides a brief intro-duction to biological fuel cells along with their envis-aged applications. A fuel cell is an electrochemical device that continuously
