Abstract
Used dimensionally stable electrodes having a valve-metal base and an originally conductive and electrocatalytic coating of e.g. ruthenium-titanium oxide are cleaned and activated by impregnation with a relatively dilute solution preferably containing only a decomposable platinum-group metal compound, followed by heating to enrich the old coating with platinum-group metal/oxide. A new outer electrocatalytic coating which is the same as or similar to the old coating is then applied on top.
