A method for producing a membrane electrode assembly for a fuel cell includes providing a first component of the membrane electrode assembly as part of a continuous material web which passes through a plurality of processing stations and connecting a second component of the membrane electrode assembly to the first component by a firmly bonded connection.

Method and device for producing a membrane electrode assembly for a fuel cell

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.

Method for coating a substrate with a spray material and functional layer achievable with this method

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.

Wire-type spray material for a thermally sprayed layer having a pearlite, bainite, martensite structure

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

Wire-like spray material, functional layer which can be produced therewith and process for coating a substrate with a spray material

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