Abstract
The deterioration of a palladium oxide type anode caused by stopping the operation of a diaphragm type electrolytic cell in the electrolysis of an alkali metal chloride is prevented by increasing the concentration of hypochlorite ions in the anolyte to give a predominant anode potential in short circuit state higher than the reduction potential of palladium oxide.
