Abstract

A stable oxygen electrode which is in an active state and retains said activity for a long service life. The electrode comprises an electrode carrier and an activated transition metal chelate of 5,14-dihydrodibenzo(5,9,14,18)tetraaza(14)annulene. Said metal chelate is activated by heating in an inner gas atmosphere at a temperature of between about 600.degree. and 1000.degree.C for at least 5 minutes.
