Abstract (en)
[origin: EP0384194A2] The invention relates to dimensionally stable anodes consisting of a) an electrically conductive valve metal, b) a conductive interlayer, and c) an electrode coating composed of an electrocatalytically active substance, the interlayer consisting of one or more noble metals and/or noble metal alloys which have been deposited on the valve metal by electrodeposition from melts containing noble metal salts.
