Patent number: 10751667Abstract: A membrane assembly for the permeative separation of a fluid from fluid mixtures includes a porous, fluid-permeable, metallic support substrate, a membrane that is disposed on the support substrate and is selectively permeable to the fluid to be separated off, and a connecting part which is formed, at least on the surface, of a fluid-tight, metallic material. The support substrate is cohesively bonded along a peripheral section thereof to the connecting part. A ceramic, fluid-permeable, porous, first intermediate layer is disposed between the support substrate and the membrane. At least one ceramic bonding layer is disposed directly on the connecting part and the material bond and extends at least over the cohesive material bond and an adjoining section of the connecting part. The first intermediate layer ends on the bonding layer and has a greater average pore size than the bonding layer.Type: GrantFiled: December 19, 2016Date of Patent: August 25, 2020Assignee: Plansee SEInventors: Markus Haydn, Stephan Hummel, Marco Brandner

Patent number: 9048498Abstract: The substrate-supported anode for a high-temperature fuel cell comprises an at least three-layer anode laminate on a metallic substrate. Each of the layers of the anode laminate comprises yttria-stabilized zirconia and nickel, wherein the mean particle size of the nickel decreases from one layer to the next as the distance from the substrate increases. The last layer of the anode laminate, which is provided for contact with the electrolyte, has a root mean square roughness of less than 4 ?m. The overall mean pore size of this layer is typically between 0.3 and 1.5 ?m. Starting powders having a bimodal particle size distribution of yttria-stabilized zirconia and nickel-containing powder are used at least for the first and second layers of the anode laminate. The mean particle size of the nickel-containing powder is reduced from one layer to the next, whereby it is advantageously no more than 0.5 ?m in the last layer of the anode laminate.Type: GrantFiled: November 4, 2010Date of Patent: June 2, 2015Assignee: Forschungszentrum Juelich GmbHInventors: Robert Muecke, Norbert H.
