CATHODE FOR USE IN ELECTROLYTIC CELL

摘要

A cathode wherein the electrocatalytically-active outer layer is of substantially uniform thickness and has contours which are at least substantially the same as the contours of the substrate immediately underlying it. The electrode may be prepared by depositing the electrocatalytically-active outer layer by physical vapour deposition. The electrocatalytically-active outer layer comprises (a) cerium and/or cerium oxide and at least one non-noble Group 8 metal or (b) platinum and/or platinum oxide and ruthenium and/or ruthenium oxide.
