Abstract
A microbial fuel cell includes an anode portion having an anode and a cathode portion having a cathode. The anode is configured to support an electrically conductive biofilm matrix. A cation exchange membrane is positioned between the anode and the cathode. The anode portion and the cation exchange membrane define an anode chamber having a volume of between about 1 μL and about 100 μL and configured to receive an anolyte. The cathode portion and the cation exchange membrane define a cathode chamber having a volume of between about 1 μL and about 100 μL and configured to receive a catholyte. The microbial fuel cell is configured to achieve a Coulombic efficiency of at least 30% and/or a power density of at least of 4.7 μW/cm. The microbial fuel cell is a microelectromechanical system and can be fabricated in an automated production process.
