DETAILED DESCRIPTION - The method for producing a catalytically coated plate-heat exchanger, which is flowed-through by two media, comprises catalytically reacting one medium to another medium, which is a process energy required for the process and set by heat conduction and/or radiation directly for disposal, where the heat exchanger are impacted areas made of stainless steel, and applying a coating having a catalyst in an aqueous or gaseous solution on the heat exchanger by electrochemical pulse deposition in an assembled state. A washcoat dispersion is introduced on the heat exchanger before the catalytic coating on an individual plate, where calcination of the washcoat dispersion mutually occurs with a connection by soldering the heat exchanger. Instead of the washcoat dispersion, a metallic layer is sintered at high temperatures and is applied on the heat exchanger forming a large surface. The catalytic coating of the different media feedthroughs in the heat exchanger is applied with two different solutions after each other. Instead of the electrochemical pulse deposition, a chemical galvanic deposition and/or a galvano-electrical micro-deposition are utilized. A hydroforming process, in which extremely thin plate strengths are realized, is used for the production of the metallic heat exchanger plates. A microstructure is introduced using the hydroforming process for the production of the metallic heat exchanger plates and enables adhesion of the wash coats and/or the catalytic coating on the plates. The heat exchanger is coated with a catalytic burner coating and an anode exhaust gas burner coating on the channels of the medium, and is coated with a soot filter coating and a catalytic reforming coating on the opposite channels. The heat exchanger is coated with the catalytic coating on the channels of the medium for an exothermic reaction and is coated with the catalytic coating on the opposite channels for an endothermic reaction.
