    Abstract: A cell structure includes a cathode, an anode, and a protonically conductive solid electrolyte layer between the cathode and the anode. The solid electrolyte layer contains a compound having a perovskite structure and containing zirconium, cerium, and a rare-earth element other than cerium. If the solid electrolyte layer has a thickness of T, the elemental ratio of zirconium to cerium at a position 0.25T from a surface of the solid electrolyte layer opposite the cathode, Zr C /Ce C , and the elemental ratio of zirconium to cerium at a position 0.25T from a surface of the solid electrolyte layer opposite the anode, Zr A /Ce A , satisfy Zr C /Ce C > Zr A /Ce A , and Zr C /Ce C > 1.
