Abstract
In the electrolytic metal coating of a strip-shape metal substrate, the substrate is passed in a continuous process as cathode through an electrolytic coating apparatus having an insoluble anode, the cathode and anode being connected to an external voltage source so that metal ions are deposited onto the substrate from an acidic electrolyte between the cathode and anode. To increase the anode service life and reduce power consumption, a hydrogen-providing gas, e.g. molecular hydrogen, is fed to the anode and a catalyst is available at the anode, so that under the influence of the catalyst electrons and hydrogen ions are formed from said hydrogen-providing gas, the hydrogen ions passing into the electrolyte.
