摘要： A method for producing a catalytic converter includes depositing a layer of catalytically active metallic material by electrochemical deposition on a planar substrate by immersing the substrate in an electrolyte that contains the catalytically active metallic material. A high overvoltage at which a large number of seeds of the metallic material are formed on the substrate is set for a predetermined first time period between the substrate and the opposing electrode. The overvoltage is reduced for a predetermined second time period to a value at which the seeds which are deposited in the first time period grow on the substrate.
