Publication number: 20240102189Abstract: A separator plate for an electrochemical system, an electrolyzer, a bipolar plate comprising such a separator plate, an electrolyzer comprising such a separator plate, and to tooling for producing such a separator plate. The separator plate comprising a flow area having a plurality of integrally formed support structures. An outer contour of the support structures in each case comprises: a first circular arc-shaped portion and a second circular arc-shaped portion, wherein a circular arc center point of the first circular arc-shaped portion and a circular arc center point of the second circular arc-shaped portion are arranged at a distance from each other on a longitudinal axis of the respective sup-port structure, and a joining portion which joins together the first circular arc-shaped portion and the second circular arc-shaped portion, wherein a width of the joining portion is smaller than a diameter of the first and/or second circular arc-shaped portion.Type: ApplicationFiled: September 22, 2023Publication date: March 28, 2024Inventors: Jonas LEISCHER, Christoph SPECHT, Stephan WENZEL, Hans WALDVOGEL, Wilhelm KUHN, Oliver CLAUS, Franz SCHWEIGGART

Patent number: 9518659Abstract: The present invention relates to a flat gasket with filter elements. In order to fulfill the increased requirements with respect to cleanliness, there is an increased demand for the integration of filter elements in flat gaskets. The corresponding filter elements mainly serve for picking of impurities accrued during production as well as other residues circulate via the operational fluids, especially during the initial period of operation of an internal combustion engine or a vehicle.Type: GrantFiled: April 5, 2012Date of Patent: December 13, 2016Assignee: Reinz-Dichtungs-GmbHInventors: Georg Egloff, Oliver Claus, Hans Waldvogel, Andreas Helfenbein, Robert Blersch
