Abstract
A method for producing a cell structure includes: a step of firing a laminated body of a layer containing an anode material and a layer containing a solid electrolyte material, to obtain a joined body of an anode and a solid electrolyte layer; a step of laminating a layer containing a cathode material on a surface of the solid electrolyte layer, and firing the obtained laminated body to obtain a cathode. The anode material contains a metal oxide Ma1 and a nickel compound. The metal oxide Ma1 is a metal oxide having a perovskite structure represented by A1x1B11-y1M1y1O3-δ (wherein: A1 is at least one of Ba, Ca, and Sr; B1 is at least one of Ce and Zr; M1 is at least one of Y, Yb, Er, Ho, Tm, Gd, In, and Sc; 0.85≤x1≤0.99; 0<y1≤0.5; and δ is an oxygen deficiency amount).
