PURPOSE:To improve separation and recovery efficiencies and reduce occurrence of trouble, by providing Pd alloy membrane pipes and a means for absorbing expansion and contraction of the pipes, etc., and enable pressure feeding of a treated gas into the interior of the pipes. CONSTITUTION:This inner pipe pressurizing type device for purifying hydrogen is formed from a vessel outer cylinder 2 equipped with an equalizing vessel 9, Pd alloy membrane pipes 5, a means 7 for leading a gas permeated to the outside of the pipes 5 to the outside of the above-mentioned outer cylinder 2, a means 6 for discharging the uppermeated gas to the outside of the aforementioned outer cylinder 2 and means 12 for absorbing expansion and contraction. The above-mentioned Pd alloy membrane pipes 5 are provided so as to flow hydrogen isotopic Gas (Ga), containing impurities and introduced into the interior of the aforementioned outer cylinder through the interior thereof. The above-mentioned means 12 for absorbing expansion and contraction are provided on the aforementioned outer cylinder 2 and vessel 9 to absorb the expansion and contraction of the above-mentioned Pd alloy membrane pipes 5.
