Abstract
The cathode, used e.g. in the prodn. of Cl2 and H2 by electrolysis of brine, has a microporous surface that is produced by (a) coating a cathode core (I) with a metal (II) selected from Ni, Co, Cr, Mn and Fe, alloyed with a secondary, less noble, removable metal (III), and (b) removing at least a part of (III). The cathode has a food resistance to corrosion and a low hydrogen overvoltage.
