Patent number: 6716551Abstract: In a method of manufacturing a fluid diffusion layer for a solid polymer electrolyte fuel cell, a surface of the fluid diffusion layer is abraded so that the topography of the fluid diffusion layer surface is rendered more uniform. The fluid diffusion layer comprises a porous substrate, and may also comprise a carbon-containing sublayer, as well as hydrophobic material. The particles formed by the abrading operation may be deposited into at least some of the pores of the substrate to form a support structure for the direct depositing of a catalyst onto the abraded surface.Type: GrantFiled: May 2, 2001Date of Patent: April 6, 2004Assignee: Ballard Power Systems Inc.Inventors: Volker Peinecke, Jorg von der Osten-Fabeck, John Robert Gordon, Herwig Robert Haas

Patent number: 6242122Abstract: An electrode-electrolyte unit for a fuel cell which prevents the permeation of the fuel used or the permeation of water through the electrolyte layer. An electrolyte is subdivided into two electrolyte layers with a barrier layer disposed between them. The barrier layer is permeable only to protons and may be coated with a catalytically active porous layer having a high effective surface area. A porous layer on the side of the unit facing the cathode increases the electrochemically active surface area and a porous layer on the side of the unit facing the anode ensures that a sufficient amount of hydrogen is dissolved. The fuel used can be hydrogen or methanol and suitable electrolytes include membranes or other solid or liquid electrolytes.Type: GrantFiled: August 3, 1999Date of Patent: June 5, 2001Assignee: Forschungszentrum Julich GmbHInventors: Hendrik Dohle, Volker Peinecke, Ilona Busenbender, Thorsten Kels

Patent number: 5959190Abstract: A sensor is provided for precisely measuring the composition of mixtures of hydrogen and oxygen gas. The sensor has an active surface, at which hydrogen and oxygen are catalytically converted into water. A transport inhibiting barrier is disposed on the active surface. The heat released during the conversion is measured, and is indicative of the mixture composition.Type: GrantFiled: November 6, 1997Date of Patent: September 28, 1999Assignee: Deutsche Forschungsanstalt fuer Luft-und Raumfahrt e.v.Inventors: Volker Peinecke, Paul Mohr

Patent number: 5723086Abstract: The present invention relates to electrode membranes which comprise an ion-exchange material forming a core zone, with electrodes bonded thereto on both sides, the ion exchange material being formed from homopolymers soluble in solvents, or copolymers or mixtures thereof. The polymers must have at least one residue dissociable in ions. The electrode material is connected on either side of the core zone to the ion-exchange material to form an intimate contact between the electrode and the ion exchange materials, while the external sides of the electrode are pure electrode material. The electrode membranes are useful for forming fuel cells or electrolyzers.Type: GrantFiled: July 12, 1995Date of Patent: March 3, 1998Assignee: Fraunhofer-Gesellschaft Zur Forderung Der Angewandten Forschung E.V.Inventors: Konstantin Ledjeff, Roland Nolte, Michael Bauer, Falko Mahlendorf, Volker Peinecke
