  • Microbial electrolysis cells and methods for the production of chemical products
    Patent number: 9216919
    Abstract: A microbial electrolysis cell having a brush anode is described. A method of producing products, such as hydrogen, at the cathode of the microbial electrolysis cell is also provided. The microbial electrolysis cell is configured in a cylindrical shape having an anode, cathode and anion exchange membrane all disposed concentrically. A brush anode spirally wound around the outside of the cylindrical microbial electrolysis cell is described. The method may include sparging the anode and/or cathode with air in some cases. In addition, CO2-containing gas may be injected into a cathode chamber to reduce pH is some cases.
