Abstract: The invention relates to a method for producing a membrane electrode assembly (12) for a fuel cell, wherein at least one first component (18) of the membrane electrode assembly (12) is provided as part of a continuous material web which passes through a plurality of processing stations. At least one second component (26) of the membrane electrode assembly is connected to the at least one first component. At least one adhesive is applied to at least one of the components (18, 26), said adhesive causing the connection of the at least one first component (18) to the at least one second component (26). Furthermore, the invention relates to a device (10) for producing a membrane electrode assembly (12).

Abstract: A method for coating a substrate, in which a wire-shaped spray material is melted in an electric arc and is deposited as a functional layer on the substrate. The invention also relates to a functional layer which can be produced on the substrate by this method. The functional layer has a high hardness value and good corrosion resistance on exposure to diesel fuel with a high sulphur proportion.

Abstract: A wire-form spray material, in particular for arc wire spraying, essentially comprising iron. The spray material is formed at least with carbon as a microalloy such that upon solidification of the spray material a fine pearlitic, bainitic, martensitic structure arises in which finely dispersed nitrides are present.

Abstract: A wire-like spray material (4) based on an iron for electric arc wire spraying and also a functional layer (2) which can be produced therewith on a substrate (1). The functional layer (2) has good corrosion resistance towards diesel fuel having a high sulphur content.

Abstract: The invention relates to an inner burner (1) for electric arc wire spraying of hollow spaces, particularly cylinder bearing surfaces (9), comprising two meltable electrodes which are supplied in two feed channels (5) to a discharge nozzle (6) of the inner burner (1). The two electrodes are connected to two sliding contacts (4) for electrical energy transmission. According to the invention, the two sliding contacts (4) are displaceably mounted in the axial direction (10) and are each connected to a guide element (7) which is also displaceably mounted in the axial direction (10). The respective guide element (7) is axially pretensioned via at least one associated spring (11) and thereby presses the sliding contact (4) against the electrode, wherein the feed channels (5), the sliding contacts (4) and the guide elements (7) are arranged parallel to one another in the spraying head (2).

Abstract: The invention relates to a fuel cell (1) with a membrane electrode assembly (2). The membrane electrode assembly (2) is disposed between two bipolar plates (5, 6) and connected to a sealing element (3). The sealing element (3) and the bipolar plates (5, 6) contact each other with the formation of an abutment region (10). A sliding surface (11) is provided in the abutment region (1), by means of which the membrane electrode assembly (2) disposed between the two bipolar plates (5, 6) can be impacted with a shear stress (15) upon compression of the two bipolar plates (5, 6). The invention further relates to a fuel cell stack with such a fuel cell (1) and to a method for sealing a fuel cell (1).
