Abstract: A method may produce a perovskite-type ceramic compact including a perovskite-type ceramic having an alkaline earth metal element, at least one element selected from Ti, Zr, and Hf, and O. Such a method may include a contact reaction process in which a precursor compact including singly a gel including water and an oxide of at least one element selected from Ti, Zr, and Hf, and a liquid containing a hydroxide of the alkaline earth metal element are brought into contact with each other.

Abstract: An electrolyte of a solid oxide cell is required to be capable of suppressing both gas cross-leak and electron leak. In addition, it is important from the viewpoint of a reduction in material costs and in the electric resistance of the electrolyte that the electrolyte is made into a thin film and that no expensive noble metal is used. The present invention provides a thin-film-shaped proton conducting electrolyte capable of suppressing both gas cross-leak and electron leak, a solid oxide cell using the proton conducting electrolyte, and a manufacturing method for the proton conducting electrolyte and the solid oxide cell. A proton conducting electrolyte using an oxide material having proton conductivity is provided. The proton conducting electrolyte includes a first portion containing Me (Me=at least any one of Ti, Mn, Fe, Co, Ni, and Cu), and a second portion different in Me content from the first portion.
