In order to make a process available for the production of a multi-layer electrode or electrode assembly, with which an electrode or electrode assembly optimized for the respective use may be produced in a simple and, in particular, inexpensive manner it is suggested that a first layer be rolled onto a carrier and at least one additional function layer be produced by spraying on a powder.

Process for production of multi-layer electrode or electrode assembly and gaseous diffusion electrode

In order to create a device for testing a membrane electrode assembly, by means of which fabricated membrane electrode assemblies can be tested in a non-destructive manner, a first contact device is provided for bringing a first electrode side of the test object into electrical contact, a second contact device is provided for bringing a second electrode side of the test object into electrical contact, the first and second contact devices being electrically conductive at least in the contact area, and the first contact device and/or the second contact device having a plurality of electrically conductive contact segments spaced from one another, and a conductivity measuring device is provided for measuring the conductivity of the test object segmentwise in a location-resolved manner.

In order to improve a process for the production of a composite consisting of electrode material, catalyst material and a solid-electrolyte membrane for an electrochemical cell, in particular a fuel cell, with which solid-electrolyte material is brought into pore-deep contact with the electrode material and the catalyst material by softening it, such that this can be carried out as effectively and inexpensively as possible it is suggested that a catalytic powder comprising electrode material, catalyst material and the solid-electrolyte material be produced, that a catalytic layer be produced on a carrier from the catalytic powder, that the catalytic layer be heated on a side facing away from the carrier to soften the solid-electrolyte material and that subsequently the catalytic layer be applied under pressure to the solid-electrolyte membrane while the solid-electrolyte material is still softened in order to form a composite.
