  • Membrane and electrode structure for methanol fuel cell
    Patent number: 5958616
    Abstract: The invention provides devices and techniques for reducing or eliminating fuel crossover from the anode to the cathode in fuel cells using organic fuels. The invention particularly provides proton exchange membranes having passages or channels with or without a catalyst layer active for the electrochemical oxidation of a fuel. The invention reduces fuel crossover by providing void spaces within the membrane where the fuel may be sequestered as it diffuses through the membrane from the anode to the cathode. The sequestered fuel may be removed physically and/or electrochemically. The invention provides for physical removal of the sequestered fuel by means of flowing a gas stream or a liquid stream through the passages thus evacuating the fuel before it diffuses to the cathode.
