Abstract

In an electrolytic cell having an anolyte compartment, a catholyte compartment, a permionic membrane therebetween and the cathode contacting the permionic membrane, the cathodic surface of the permionic membrane has a conductive, substantially non-electrocatalytic current distributing material, (e.g. Cu, Ag, Au or Ag2O), dispersed across the face thereof. The cathode may comprise a Group VIII transition metal electrocatalyst having a lower hydrogen evolution overvoltage than the non- electrocatalytic material. In alternative embodiments: (a) the non-electrocatalytic material is bonded to the membrane, the electrocatalyst being present either as a second layer on top of the non- electrocatalytic material or on a separate electrode structure; (b) the electrocatalyst is present on the surface of the membrane in admixture with the non- electrocatalytic material; (c) the electrocatalyst and the non- electrocatalytic material are both present on and adherent to an electroconductive substrate, and removable from the membrane. f
