The invention relates to a method for producing a supported catalyst material for a fuel-cell electrode, as well as a catalyst material that can be produced using said method. In the method, first, a carbide-forming substance is deposited from the gas phase onto the carbon-based carrier material to produce a carbide-containing layer and, then, a catalytically-active precious metal or an alloy thereof from the gas phase is deposited to form a catalytic layer. By chemical reaction of the carbide-forming substance with the carbon, very stable carbide bonds are formed at the interface, while an alloy phase of the two forms at the interface between carbide-forming substance and precious metal. Overall, a very stable adhesion of the catalytic precious metal to the substrate results, whereby degradation effects are reduced, and the life of the material is extended.
