SOLID ELECTROLYTE MEMBER, SOLID OXIDE FUEL CELL, WATER ELECTROLYSIS DEVICE, HYDROGEN PUMP, AND METHOD FOR PRODUCING SOLID ELECTROLYTE MEMBER
Provided is a proton-conductive solid electrolyte member having a structure in which an electrolyte layer and an anode layer are laminated. The electrolyte layer contains a metal oxide having a perovskite crystal structure. The anode layer contains Fe2O3and the metal oxide. The metal oxide is a metal oxide expressed by the following formula [1], or a mixture or a solid solution of a metal oxide expressed by the following formula [1]: AaBbMcO3-δ, where A denotes at least one element selected from the group consisting of Ba and Ca; B denotes at least one element selected from the group consisting of Ce and Zr; M denotes at least one element selected from the group consisting of Y, Yb, Er, Ho, Tm, Gd, In, and Sc; a is a number satisfying 0.85 ≤ a ≤ 1; b is a number satisfying 0.50 ≤ b < 1; c is a number satisfying c = 1 - b; and δ is an oxygen deficiency amount.
