1. A hydrogen-permeable membrane comprising:
- a permeable layer through which hydrogen is permeatable; and
a catalyst layer which promotes permeation of hydrogen in the permeable layer, and which is provided on at least one surface of the permeable layer so as to form a surface layer of the hydrogen-permeable membrane, and whose contact area that contacts gas is larger than an area of the permeable layer.

Abstract
A hydrogen-permeable membrane includes a permeable layer which has a function of making hydrogen permeate therethrough, and a catalyst layer which acts as a catalyst for promoting permeation of the hydrogen in the permeable layer. An area of the catalyst layer which contacts gas is larger than an area of the permeable layer.

10. A hydrogen-permeable membrane comprising:
-
a permeable layer which contains a Group VA element and through which hydrogen is permeatable; and
a catalyst layer which promotes permeation of hydrogen in the permeable layer, and which is provided on at least one surface layer of the permeable layer to form a surface of the hydrogen-permeable membrane, the catalyst layer containing at least one metal element selected from a group consisting of Ru, Rh, Ir, Pt, Re and Ni. - View Dependent Claims (11)

12. A manufacturing method of the hydrogen-permeable membrane which makes hydrogen selectively permeate therethrough, comprising
preparing a base body; -
arranging the base body in an inert atmosphere; and
sequentially forming, in the inert atmosphere, a first layer which contains Pd on the base body, a second layer which contains a Group VA element on the first layer, and a third layer which contains Pd on the second layer. - View Dependent Claims (13, 14)
