摘要：

When electrolytic catalysts produced by pyrolysis of cobalt tetraazaannulenes on active carbon are stored in air, a decrease of the electrolytic activity is observed. This deterioration is the result of irreversible absorption of oxygen from air. This oxidation of electrode materials which are very active in the cathodic reduction of oxygen can only be prevented by storage under a protective atmosphere or by immediate applications.
