[Perspective oxide materials for anode of low-temperature electrochemical oxygen regeneration system].

The paper summarizes results of substantiating, selecting, developing, manufacturing and testing of oxidic multicomponent surface compositions with the perovskite structure on porous titanium matrixes proposed for use in anodes of low-temperature electrochemical systems with a liquid electrolyte. Electrochemical activity of 88 oxide layers was evaluated as a function of composition, concentration and temperature of the carbonate electrolyte, elementary content of oxidic composition, and physical/chemical characteristics of the crystal structure. It was shown that the electrode process can be controlled by changing components of the electrolyte or complexity of the multicomponent oxidic surface compositions.
