The invention is related to a method for bonding components of a PEM fuel cell with a frame and/or amongst one another, wherefore an adhesive curable by electromagnetic radiation in the range of visible light or UV is applied to the frame and/or the at least one component. The invention is characterized in that the adhesive is activated by the electromagnetic radiation and heated after the frame and/or components are brought into contact; or the frame and/or the components are brought into contact and the adhesive is exposed to electromagnetic radiation for activating and heating; to reduce its viscosity before the adhesive is finally cured. The adhesive is a cationic epoxy which contains water.

A method of producing a rubber seal includes placing a screen with an opening, above a workpiece including a base portion and a bead base protruding from the base portion and applying a liquid material for forming the rubber seal, onto a top part of the bead base through the opening. In the production, the liquid material is applied onto the top part by moving a squeegee along a surface of the screen in a state where a stopper portion is disposed at a position adjacent to the bead base within an area of the base portion and between the screen and the workpiece.
