Process for producing a catalyst layer on a carrier and a catalyst produced therefrom

In a process for the formation of a metallic catalyst layer which is utilized for the removal of hydrogen from a gas mixture containing hydrogen and oxygen, said catalyst layer being constituted from a metal or metal alloy catalytically influencing the oxidation of the hydrogen;

• and a carrier material having said catalyst layer applied thereon, wherein said carrier material is a metallic carrier plate;
• the improvement wherein said catalyst layer is a metallic material selected from the group consisting of palladium, platinum and palladium-nickel alloys and is a porous catalyst layer coated at least in a partial region onto the carrier material by plasma spraying or flame spraying, wherein the catalyst layer formed thereby has tunnels within the catalyst layer separated from the surrounding atmosphere by catalyst material, and has pores connecting said tunnels to the external surface of the catalyst layer.
