A simple representation of the anaerobic (anode portion) and aerobic (cathode portion) biological degradation simultaneous to electricity generation in a single chamber microbial fuel cell is shown within the figure above. The anode portion consists of an oxidation/reduction process from bacterium which produce a hydrogen gradient and allow hydrogen protons to diffuse to the cathode portion to balance out the pH of the organic matter or wastewater. The cathode portion also consists of this oxidation/reduction process; however, since the cathode allows oxygen to diffuse from the ambient air to the inside portion of the single chamber MFC, water is automatically formed in absence of any hydrogen proton gradient formation. The energy available from the proton gradient due to the anode can be harnessed by connecting a circuit from the anode to the cathode to allow the electron, oxygen and the hydrogen protons to catalytically form water via a platinum catalyst.
