  • Publication number: 20240102189
    Abstract: 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.

  • Patent number: 9897038
    Abstract: The invention relates to a sealing system consisting of a first part and a second part and at least a passage opening extending in both parts, in particular a passage opening for fluids such as hot combustion gases from combustion engines as well as a corresponding metallic flat gasket such that the sealing system comprises or consists of a first part and a second part with the first part and the second part being compressed against each other at a joint contact surface and comprising at least one passage opening in the contact surface, which protrudes into the first and/or second part, an annular groove, which is delimited by the first and the second part and which encircles the passage opening, with the first and second part in the area at least radially outside of the groove come to rest one on the other.

  • Patent number: 9518659
    Abstract: 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.
