To provide a hydrogen permeation structure having a hydrogen permeative base material and an oxide proton conductive film, excellent in tight adhering property between the hydrogen permeative base material and the oxide proton conductive film, hardly generating exfoliation of the oxide proton conductive film, and to provide a manufacturing method of the same and a fuel cell using the same.
The hydrogen permeation structure is composed of the hydrogen permeative base material, an oxide proton conductive film, and an intermediate layer on both surfaces of which the hydrogen permeative base material and the oxide proton conductive film are adhered respectively. The intermediate layer contains a main element A constituting an intermediate layer side surface part of the hydrogen permeative base material, and a main metallic element B contained in constituent element of the oxide proton conductive film. The ratio of the number of atoms A/B of the A and B is not less than 0.1. The manufacturing method of the same and the fuel cell using the same are provided.
