A microbial fuel cell (MFC) is a bio-electrochemical system[1] that drives an electric current by using bacteria and a high-energy oxidant such as O2,[2] mimicking bacterial interactions found in nature. MFCs can be grouped into two general categories: mediated and unmediated. The first MFCs, demonstrated in the early 20th century, used a mediator: a chemical that transfers electrons from the bacteria in the cell to the anode. Unmediated MFCs emerged in the 1970s; in this type of MFC the bacteria typically have electrochemically active redox proteins such as cytochromes on their outer membrane that can transfer electrons directly to the anode.[3][4] In the 21st century MFCs have started to find commercial use in wastewater treatment.[5]
