Zusammenfassung:	PURPOSE:To obtain high-purity hydrogen by permeating the hydrogen prepared by steam reforming a hydrocarbon or methanol through a hydrogen separating functional membrane and taking out the hydrogen accompanied with an inert gas or further steam. CONSTITUTION:A hydrocarbon or methanol is fed to a reforming catalyst layer 4 filled in a space divided with a reaction tube 1 and a hydrogen separating functional membrane 3. Steam reforming is then carried out to produce hydrogen, which is subsequently permeated through the functional membrane 3 and mixed with an inert gas or the inert gas and steam or a circulating gas 6 and taken out of the system. On the other hand, the impermeable (unreacted) gas 8 discharged from the catalyst layer 4 is circulated, fed to a space between the reaction tube 1 and an outer cylinder 2 and burned to heat the aforementioned catalyst layer 4. The resultant gas 8 is then discharged as a combustion waste gas 10 to the outside of the system.
