Abstract
A cathode for electrolytic processes, particularly suitable for hydrogen evolution in chlor-alkali electrolysis comprises a metal substrate provided with a catalytic coating made of two layers containing palladium, rare earths (such as praseodymium) and a noble component selected between platinum and ruthenium. The rare earth percent amount by weight is lower in the outer layer than in the inner layer.
