Title: Method of and apparatus for electrolytic treatment of metal

Abstract: An electrolytic process and a cathode structure for use in the process for treatment of an elongated strip of metal as the strip is passed between an anode immersed in an acidic anolyte solution and a cathode immersed in a basic catholyte solution separated from the anolyte solution by an ion-permeable membrane. The cathode structure includes means for directing a flow of the catholyte solution through a chamber enclosing a negatively-charged cathode plate to cool the structure and to remove hydrogen gas which is evolved on the active cathode surface to increase the efficiency of the electrolytic process.
