摘要： A hydrogen permeable module includes a hydrogen permeable membrane that permeates hydrogen, an outer peripheral part of the hydrogen permeable membrane being restricted, an inside of the outer peripheral part of the hydrogen permeable membrane being not restricted. The hydrogen permeable module permeates the hydrogen by constantly keeping a pressure of a primary side to a pressure that is equal to or more than a pressure of a secondary side. The inside of the outer peripheral part of the hydrogen permeable membrane is not restricted so as to be capable of expanding to the secondary side.

The Nb—Ti—Co alloy is preferably subjected to heat treatment at 800° C. or more so that the eutectic structure in the casted state can be changed to a granular structure. The Nb—Ti—Co alloy used there is preferably NbxTi(100-x-y)Coy, (x≦70, 20≦y≦50 (mol %)).
