Abstract

Process for depositing metals, employing an electrolytic bath which has an anolyte and a catholyte which are separated by a cation exchange membrane. The membrane consists of a perfluorinated film. The anolyte preferably contains a depolarising addition in order to reduce the electrode potential of the anode. The pH of the anolyte is set in such a way that a transfer of hydrogen through the membrane takes place which compensates for the generation of hydrogen on the cathode while the bath is used. The anode is arranged in the bath within a sheath which consists at least in part of a perfluorinated cation exchange membrane. The anolyte is likewise situated within the sheath.
