Patent number: 9583772Abstract: The present invention relates to high-temperature solid oxide fuel cells, in particular to rotationally symmetrical high-temperature solid oxide fuel cells. The inventive oxide-ceramic high-temperature fuel cell having one or more gas channel(s) open at at least one end. The fuel cell has a substrate surrounding the gas channel(s) at least sectionally, preferably completely. The gas channel(s) and/or the substrate surrounding the gas channel(s) has/have (a) changing cross-sections(s), preferably (a) conically tapering cross-section(s), seen in the direction of the longitudinal axis/axes of the gas channel(s).Type: GrantFiled: May 28, 2010Date of Patent: February 28, 2017Assignee: EZELLERON GMBHInventors: Sascha Kuehn, Katrin Klein, Gerhard Buchinger

Patent number: 8361295Abstract: The invention relates to a method for producing metallic moulded bodies comprising a ceramic layer according to the membrane method, whereby a porous metallic membrane is used. The aim of the invention is to provide a cost-effective, rapid method which is as non-polluting as possible for producing metallic moulded bodies comprising a ceramic layer according to the membrane method using a porous metallic membrane, whereby the penetration depth, the green density and the deposition speed of the ceramic particles in the metallic membrane can be controlled. To this end, the porous metallic membrane is sealed by electrophoretic deposition of ceramic particles in the pores of the metallic membrane, the metallic membrane being arranged between two electrodes for the electrophoretic deposition, and the space between an electrode and the metallic membrane being filled with a dispersion containing the ceramic particles to be deposited in the pores and a dispersant.Type: GrantFiled: January 23, 2004Date of Patent: January 29, 2013Assignee: eZelleron GmbHInventors: Rolf Clasen, Sascha Kühn
