## Abstract

A catalytic arrangement for an electrolyzer system or a fuel cell system includes a catalyst support unit and a catalyst layer, wherein the catalyst layer has a carbon matrix with a metal, non-metal and/or metalloid doping.

## Claims

### Claim 1

A catalytic arrangement for an electrolyzer system or a fuel cell system, comprising a catalyst support unit and a catalyst layer, wherein the catalyst layer has a carbon matrix with a metal, non-metal and/or metalloid doping, wherein the doping includes aluminum (Al) or tin (Sn).

### Claim 2 (depends on 1)

The catalytic arrangement according to claim 1, wherein the catalyst support unit has stainless steel.

### Claim 3 (depends on 1)

The catalytic arrangement according to claim 1, wherein the catalyst support unit has a foam or a mesh comprising one or more transition metals of the fourth to sixth period.

### Claim 4 (depends on 1)

The catalytic arrangement according to claim 1, wherein the doping includes one or more precious metals.

### Claim 5 (depends on 1)

The catalytic arrangement according to claim 1, wherein the doping includes one or more transition metals of the fourth to sixth period.

### Claim 6 (depends on 1)

The catalytic arrangement according to claim 1, wherein the doping includes sulfur (S), phosphorus (P), nitrogen (N), oxygen (0), or boron (B).

### Claim 7 (depends on 1)

An electrolyzer system for water splitting and/or hydrogen peroxide development, wherein the electrolyzer system comprises a catalytic arrangement according to claim 1.

### Claim 8 (depends on 1)

A fuel cell system for an oxygen reduction reaction, wherein the fuel cell system comprises a catalytic arrangement according to claim 1.

### Claim 9 (depends on 1)

A method for producing a catalytic arrangement according to claim 1, wherein the catalyst layer is deposited on the catalyst support unit with the aid of a physical vapor deposition or a chemical coating method.
