Catalytic activity of lali0.1co0.1fe0.8o3-d cathode in (Li0.62K0.38)2CO3 melt. Part II. The reaction mechanisms and catalytic activity of the oxide electrode

The oxygen reduction mechanisms on an oxide electrode are proposed. It was found, that in the temperature range 870–1020 K mechanism involving superoxide ions dominates, whereas in T < 870 К region the reaction mechanisms involving molecular oxygen apparently take place.
