SOLID ELECTROLYTIC MEMBER, SOLID OXIDE TYPE FUEL BATTERY, WATER ELECTROLYZER, HYDROGEN PUMP AND MANUFACTURING METHOD OF SOLID ELECTROLYTIC MEMBER
To provide a large-size solid electrolytic member in which a warp or crack is hardly caused, and others.SOLUTION: A solid electrolytic member is one having proton conductivity and having a structure in which an electrolyte layer 11 is laminated on one face of an anode layer 12. The electrolyte layer 11 is a layer containing a metal oxide having a perovskite type crystal structure. The anode layer 12 is a layer containing NiO and the metal oxide. The metal oxide is a metal oxide represented by the formula [1] below or a mixture or solid solution of the metal oxide represented by the formula [1]. In the solid electrolytic member, the difference of a thermal expansion coefficient of the electrolyte layer 11 in contact with the anode layer 12 from a thermal expansion coefficient of the anode layer 12 is within a range of 2.5×10K. ABMOFormula [1] (where A represents one or more elements selected from Ba, Ca and Sr; B represents one or more elements selected from Ce and Zr; M represents one or more elements selected from Y, Yb, Er, Ho, Tm, Gd, In and Sc; 0.85≤a≤1; 0.50≤b<1; c=1-b; and δ1 is an amount of oxygen deficiency).SELECTED DRAWING: Figure 1
