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.
