摘要： Provided is a thin-film laminate structure of mixed ionic-electronic conductive electrolyte and electrode which, when used as a solid oxide cell electrolyte, enables the ionic transference number to be increased even without using a costly noble metal. The laminate structure of mixed ionic-electronic conductive electrolyte and electrode comprises a dense electrolyte layer (1), a porous electrolyte layer (2), and a porous electrode (3). The dense electrolyte layer (1) has a film thickness of 1 to 15 µm and a relative density of 95 to 100 vol%, and contains a first oxide having mixed ionic-electronic conductivity. The porous electrolyte layer (2) is laminated on the dense electrolyte layer (1), has a film thickness of 1 to 10 µm and a relative density of 30 to 90 vol%, and contains a second oxide having mixed ionic-electronic conductivity. The porous electrode (3) is laminated on the porous electrolyte layer.

摘要： 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.
