  • Microbial batteries with re-oxidizable solid-state electrodes for conversion of chemical potential energy into electrical energy
    Patent number: 9509028
    Abstract: A microbial battery is provided. At the anode, microbial activity provides electrons to an external circuit. The cathode is a solid state composition capable of receiving the electrons from the external circuit and changing from an oxidized cathode composition to a reduced cathode composition. Thus, no external source of oxygen is needed at the cathode, unlike conventional microbial fuel cells. The cathode can be removed from the microbial battery, re-oxidized in a separate oxidation process, and then replaced in the microbial battery. This regeneration of the cathode amounts to recharging the microbial battery.
