ABSTRACT:
A method for manufacturing a gas separating unit which comprises laminating a metal plate on a material capable of separating a hydrogen gas (palladium alloy foil) by cladding, etching selectively a central portion of a cut clad plate (K) using an etching solution, to thereby expose an underlying palladium alloy foil layer, and providing a metal supporting plate on the other side of the palladium alloy foil layer. The method allows the manufacture of a gas separating unit having an enhanced effective area of a material capable of separating a hydrogen gas and is excellent in the handlability of a material capable of separating a hydrogen gas during manufacturing.
