Abstract

Provided is a technique capable of suppressing occurrence of cracking in an air electrode and separation at the interface between the air electrode and a solid electrolyte layer during use of a solid oxide electrolysis cell. The air electrode of the solid oxide electrolysis cell is an air electrode containing a complex oxide having a perovskite structure. In a cross section of the air electrode, the standard deviation among measurements of each element atomic concentration of the complex oxide at 10 spots in one field of vision, the measurements being obtained by means of energy-dispersive X-ray spectroscopy, is 13.5 or less.
