PURPOSE:To ensure a great difference of hydrogen concentration between the interior and exterior of Pd alloy membrane pipes and improve dispersion and recovery efficiencies, by providing U-shaped Pd alloy membrane pipes and enabling pressure feeding of hydrogen isotope gas containing impurities into the interior of the pipes. CONSTITUTION:This inner pipe pressurizing type device for purifying hydrogen is formed from a vessel outer cylinder 2, U-shaped Pd alloy membrane pipes 5, a means 7 for leading a gas permeated to the outside of the pipe 5 to the outside of the above-mentioned outer cylinder 2, a means 6 for discharging the uppermeated gas to the outside of the above-mentioned outer cylinder 2, etc. The aforementioned 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 2 through the interior thereof.
