  • BIOANODE AND BIOCATHODE STACK ASSEMBLIES
    Publication number: 20110039164
    Abstract: A biofuel cell device for generating electrical current. The device includes a fuel manifold having a face, and at least one cavity in the face defining a fuel reservoir, an inlet in fluid communication with the reservoir for flow of fuel fluid into the manifold to fill the reservoir and an outlet in fluid communication with the reservoir for flow of fuel fluid out of the manifold. The device has an anode assembly including at least one bioanode positioned for contact with fuel fluid in the fuel reservoir, and a cathode assembly including at least one cathode positioned for flow of fuel fluid through the bioanode to the cathode. The device includes a controller operatively connected to the anode assembly and the cathode assembly for controlling the output of electrical current from the biofuel cell device.
