Hydrogen-permeable structure, method of manufacturing thereof and fuel cell using the same

摘要

A hydrogen-permeable structure is disclosed, which includes a hydrogen-permeable base in which a fluctuation range of a d value by X-ray analysis measurement is at most 0.05% in a region within 2 μm deep from a surface, and an oxide proton conductive film formed on a surface thereof. The disclosure also relates to a method of manufacturing the hydrogen-permeable structure and a fuel cell using the hydrogen-permeable structure.
