The new hydrogen-recovering device 10 has a box-shaped frame 11 made of stainless steel having a takeout pipe 12 attached to its one side. A plurality of spacers 13 are arranged inside the box-shaped frame 11 along a lengthwise direction of the device 10. A perforated metal plate 14 is fixed to each surface of the boxy- shaped frame 11, and a hydrogen-permeating membrane 16 cladded with a membrane holder 15 is further fixed to the perforated metal plate 14. Hydrogen gas as a decomposition product of hydrocarbon selectively passes through the hydrogen-permeating membrane 16 and flows through the takeout pipe 12 to the outside. A tubular device, which has the structure that a hydrogen-permeable membrane is fixed to a perforated metal plate wound around a tubular frame, is also proposed. The device 10 is light and strong, so that it is installed in a gas-reforming plant without use of a fixing jig.
