We succeeded in obtaining an air electrode with excellent polarization characteristics. That is, when polyacrylonitrile is heat-treated, it becomes a nitrogen-containing cyclic polymer as shown in the formula below, which has a dominant ability to decompose hydrogen peroxide. =pq=Sushita 7cho 01 Noah 21 Kuchi Nitokare The air electrode containing the cyclic polymer obtained by this heat treatment is obtained in the following manner.
