  • Immobilized enzymes in biocathodes
    Patent number: 8859151
    Abstract: Disclosed is an improved biofuel cell having a cathode comprising a dual function membrane, which contains an oxygen oxidoreductase enzyme immobilized within a buffered compartment of the membrane and an electron transport mediator which transfers electrons from an electron conducting electrode to the redox reaction catalyzed by the oxygen oxidoreductase enzyme. The improved biofuel cell also has an anode that contains an oxidoreductase enzyme that uses an organic fuel, such as alcohol, as a substrate. An electric current can flow between the anode and the cathode.
    Type: Grant

    Date of Patent: October 14, 2014
    Assignee: St. Louis University
