FUEL CELL, USING OXIDOREDUCTASE TYPE ENZYMES IN THE CATHODICCOMPARTMENT AND POSSIBLY IN THE ANODIC COMPARTMENT

摘要

The invention concerns a proton-exchanging membrane fuel cell comprising: a cathode compartment including a cathode, an oxidant consisting of oxygen and at least an enzymatic catalyst; an anode compartment comprising an anode, a fuel and at least a catalyst, said anode and cathode compartments being arranged on either side of said membrane. Said cell is characterized in that said enzymatic catalyst of the cathode compartment is an oxidoreductase enzyme, said enzyme being capable of catalyzing oxidation of an adequate substrate and reduction of oxygen into hydrogen peroxide, said hydrogen peroxide acting as direct acceptor of electrons from the cathode.
