Bicarbonate and Carbonate As Hydroxide Carriers in a Biological Fuel Cell

The present invention relates generally to a process that helps alleviate the pH gradient between anode and cathode compartments in any biological fuel cell or electrolytic cell configuration in which a pH gradient between anode and cathode is limiting the voltage efficiency. By providing acid to the cathode compartment in the form of CO2, the pH gradient is reduced and voltage efficiency and power output are increased. In one embodiment, carbon dioxide produced in the anode chamber is recycled to the cathode chamber.
