Abstract: The invention relates to a method of attaching a gasket (4) to a bipolar plate (12). The method comprises the steps of applying and aligning a first gasket foil (4a) to a second gasket foil (4b) having connection recesses (8), connecting the first gasket foil (4a) to the second gasket foil (4b), so that the gasket (4) is formed, placing the gasket (4) on the bipolar plate (12) so that the second gasket film (4b) with the bonding recesses (8) abuts the bipolar plate (12) and performing an embossing step in which an embossing force is applied with an embossing tool (20) in the region of the connecting recesses (8) so that an embossed adhesive point (24) is formed and the first gasket foil (4a) is bonded to the bipolar plate (12) via an adhesive means (16) arranged in the connecting recess (8) on the first gasket foil (4a).

Abstract: The present invention relates to a bipolar plate (100, 200, 403, 405, 407, 409, 500) for a fuel cell, wherein the bipolar plate (100, 200, 403, 405, 407, 409, 500) comprises at least one fluid channel (101, 103, 105, 201, 203, 205, 207, 209, 501) for transporting operating fluids of the fuel cell, wherein the at least one fluid channel (101, 103, 105, 201, 203, 205, 207, 209, 501) comprises an inlet opening for introducing fluid into the at least one fluid channel (101, 103, 105, 201, 203, 205, 207, 209, 501) and an outlet opening for fluid exiting the at least one fluid channel (101, 103, 105, 201, 203, 205, 207, 209, 501), wherein the at least one fluid channel (101, 103, 105, 201, 203, 205, 207, 209, 501) comprises a first region (107, 211, 503) and at least one second region (109, 213, 507), and wherein the at least one second region (109, 213, 503) has a cross-section which is reduced compared to the first region (107, 211, 507) in order to adjust a volumetric flow of fluid which exits the outlet opening

Abstract: The present invention relates to a fuel cell stack (10) and to a method for producing such a fuel cell stack (10). The fuel cell stack (10) comprises at least two fuel cell modules (58) with in each case at least two individual cells (5), each fuel cell module (58) having module end plates (70) on both cell stack outer sides (66), and fuel cell stack compression means (82), via which the fuel cell modules (58) stacked one on top of the other are braced to form a fuel cell stack (10).

Abstract: Disclosed here is a method for arranging at least one composite element at a component. The composite element includes a sleeve element and an insert element. The method involves: arranging the sleeve element in a bore of the component; connecting the sleeve element and the insert element so that a composite element is formed; inserting an engagement apparatus in the composite element, wherein the engagement apparatus aligns and/or assembles the sleeve element and the insert element to each other. Also disclosed here is use of an engagement apparatus and at least one composite element for arranging the composite element at a component. The at least one composite element includes a sleeve element and an insert element. The engagement apparatus aligns and/or assembles the sleeve element and the insert element to each other.
