The use of a palladium alloy membrane foil, produced by the following method, for hydrogen separation from a process gas mixture, is new. The production method involves (a) preparing electroplating baths (1,2) of different types, each containing an electrolytic solution (3,4) for deposition of one of the alloy components; and (b) forming a layer stack for the membrane foil by successive electrodeposition of alternate alloying component layers on the circumference of a rotating cathode roll (7) which is dipped in each bath. |
