Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Further details and advantages will be explained below with reference to the exemplary embodiment shown in the drawings. In the figures:

[0029] FIG. 1 shows an exemplary embodiment of a catalytic arrangement for an electrolyzer system or a fuel cell system in a schematic representation.

DETAILED DESCRIPTION

[0030] FIG. 1 shows an embodiment of a catalytic arrangement 1, which can be used as an electrode in a electrolyzer system or as part of a fuel cell system. The catalytic arrangement 1 comprises a catalyst support unit 2 and a catalyst layer 3. The catalyst support unit 2 can consist, for example, of a stainless steel or of a foam or mesh comprising one or more transition metals of the fourth to sixth period. The catalyst layer 3 is arranged above the catalyst support unit 2. This typically represents the outer part of the catalytic arrangement 1, i.e., it is free-standing on its side facing away from the catalyst support unit 2, and can thus be brought into contact with fluids. The represented catalyst layer 3 consists essentially of a carbon matrix 5 with a doping 4. It is conceivable that the catalyst layer 3 comprises several partial layers, i.e., is designed as a layer system. The doping 4 can comprise metals, metalloids, and/or non-metals. For example, the doping 4 can have one or more precious metals, such as ruthenium, iridium, and/or platinum. Alternatively or additionally, the doping can have one or more transition metals of the fourth to sixth period, such as nickel, manganese, cobalt, iron, and/or molybdenum. Alternatively or additionally, the doping can have one or more non-metals and/or one or more metalloids, such as sulfur, phosphorus, nitrogen, oxygen, and/or boron. Again, alternatively or additionally, it is possible that the doping comprises one or more further metals, such as aluminum and/or tin.

[0031] It is conceivable that the catalyst support unit 2 comprises one or more intermediate layers (not shown) adjoining the catalyst layer 3.

[0032] An exemplary embodiment of a catalytic arrangement 1 for an electrolyzer system or a fuel cell system, comprising a catalyst support unit 2 and a catalyst layer 3, is described above, wherein the catalyst layer 3 has a carbon matrix 5 with a metal, non-metal and/or metalloid doping 4.
