Abstract
Porous electrodes are obtained by a method in which a layer of a powder mixture comprising (a) finely divided carbonyl metal having a low bulk density and high frictional resistance and (b) a pulverulent component which is catalytically active or can be activated by alkali treatment, in an a/b ratio of about 3:1 to 1:3, is applied by rolling to one or both sides of a framework-forming metallic substrate having adhesion-promoting surface roughness, and said layer is consolidated by electrodeposition of metal, after which activation is finally effected if necessary. Superficial oxidation of the powder particles, which decreases from the outer surface of the layer toward the support and gradually dissolves in the electroplating bath, promotes extensive consolidation of the layer by electrodeposition.
