ELECTRODE FOR HIGH-TEMPERATURE ELECTROCHEMICAL DEVICES WITH HARD ELECTROLYTE Russian patent published in 2010 - IPC H01M4/86 H01M8/12 

FIELD: electricity.

SUBSTANCE: invention may be used as electrodes in development of electrolytic cells, fuel elements and other devices. According to invention, electrode arranged on the basis of perovskite compound with electronic conductivity with additives of electrolyte having the following composition - Bi₂O₃ -Y₂O₃ or mixture of electrolytes Bi₂O₃ - Y₂O₃ and ZrO₂ - Sc₂O₃ or Bi₂O₃ - Y₂O₃ and ZrO₂ - Y₂O₃ and applied onto surface of hard electrolyte with oxygen-ion conductivity, additionally contains between electrode and hard electrolyte intermediate layer made of mixture of bivalent and tetravalent uranium in amount of 85 - 97 wt % and hard electrolyte 3-15 wt % with thickness of 2-10 mcm.

EFFECT: improved electrochemical activity of electrodes, which exhibits in reduction of electrode polarisation resistance in cathode and anode processes.
