Patent number: 7001575Abstract: A device feeds educts to parallel spaces separated from one another by way of a distributor unit. Outlets of the distributor unit are assigned to the spaces, and evaporator structures for the evaporation of liquid media are provided in the spaces. Each outlet of the distributor unit project into a space. The boiling point of the medium in the distributor unit is maintained above the temperature of the medium in the distributor unit.Type: GrantFiled: August 13, 2001Date of Patent: February 21, 2006Assignee: NuCellSys GmbHInventors: Roland Cwik, Andreas Ebert, Oskar Lamla, Bruno Motzet, Martin Schuessler, Tomas Stefanovski, Alois Tischler, Marc Weisser

Patent number: 6830736Abstract: For carrying out a heterogeneously catalyzed reaction, such as the generation of hydrogen from hydrocarbons or alcohol, a reaction mixture comprising a hydrocarbon and water is supplied to a catalyst, which is produced by pressing at least one catalyst powder into a layer. Instead of a metallic housing, stacked layers are sealed by an edge seal, introduced into the layer or applied on the layer.Type: GrantFiled: September 15, 2000Date of Patent: December 14, 2004Assignee: Ballard Power Systems AGInventors: Oskar Lamla, Martin Schüssler

Patent number: 6808690Abstract: A catalyst element for a stacked reactor for generating hydrogen from hydrocarbons includes a catalyst disc of porous material and a solid connection element. The catalyst-side end of the connection element is at least partially enclosed by the catalyst disc and is connected to this disc. The catalyst-side end of the connection element may have a mediator layer that is joined to the connection element over the entire area by sintering, soldering, or adhesive bonding. The mediator layer is joined to the catalyst disc over the entire area by sintering. Attachment means are provided at the exposed end, which is remote from the catalyst, of the connection element.Type: GrantFiled: August 8, 2001Date of Patent: October 26, 2004Assignee: Ballard Power Systems AGInventors: Andreas Ebert, Oskar Lamla, Thomas Stefanovski

Patent number: 6644246Abstract: A device for evaporating liquids includes a porous, thermally conductive evaporation body, which contains a catalyst material on one surface, while the evaporation body is gas-impermeable on the opposite surface. Liquid which is to be evaporated and, if appropriate an additional fuel, can be fed to the evaporation body. The heat of evaporation required is provided by an exothermic reaction of the liquid or with a gaseous oxidizing agent at the catalyst material.Type: GrantFiled: September 15, 2000Date of Patent: November 11, 2003Assignee: Ballard Power Systems AGInventors: Roland Cwik, Andreas Ebert, Oskar Lamla, Martin Schuessler, Tomas Stefanovski

Patent number: 6514627Abstract: A plurality of catalyst disks pressed from porous catalyst material are stacked one on the other and together sintered with the application of pressure to make a stacked reactor for hydrogen production from hydrocarbons. To form especially tight seams the catalyst disks have projections formed in the area of contact with an adjacent catalyst disk. Hollow spaces formed in the catalyst disk or formed by two adjacent catalyst disks have a system for supporting the hollow spaces, as for example a cooper grid placed in the hollow space, which can be covered at least partially by a metal sheet or supporting bars pressed onto the catalyst disk.Type: GrantFiled: July 21, 1999Date of Patent: February 4, 2003Assignee: Ballard Power Systems AGInventors: Dietmar Heil, Oskar Lamla, Martin Schübler

Patent number: 6383469Abstract: A device for utilizing heat generated by a catalytic reaction has a first area for heating (vaporizing) at least one starting material which is to be reacted, particularly a reaction mixture. A second area is provided for at least partially carrying out the catalytic reaction or for further reaction of reaction products formed during the catalytic reaction and/or for at least partial cooling of reaction products formed during the catalytic reaction. The first area and the second area are in thermally conductive communication.Type: GrantFiled: February 23, 2000Date of Patent: May 7, 2002Assignee: Xcellsis GmbHInventors: Oskar Lamla, Carlo Saling, Martin Schuessler
