Abstract

PURPOSE: To obtain the titled anode withstanding use over an extremely long term by treating an Ni electrode having formed. Ni oxide on the surface with an Rh salt soln. and heating the treated electrode in a reducing atmosphere to firmly coat it with Rh.
CONSTITUTION: An Ni substrate electrode is calcined at ≥900°C in an atmosphere contg. O2 to form an oxide film once. This porous electrode is uniformly wetted and impregnated with an aqueous Rh salt soln. up to the interior. It is then reduced at 300W500°C in a gaseous H2 flow to deposite metallic Rh on the Ni surface, and part of the Rh is diffused in the Ni layer to form a firmly bonded layer. The preferred Ni electrode as the substrate is surface extended Ni such as porous Ni manufactured by sintering, leaching, spraying or other method. The Rh salt is a water soluble salt such as chloride or sulfate, and it is used as an aqueous soln. having about 0.05W 0.5% concn. An aqueous ammonia soln. may be heated and dissolved in the Rh salt soln. while keeping the concn.
