PROBLEM TO BE SOLVED: To provide a hydrogen purifier capable, on an occasion for purifying hydrogen by using a palladium alloy film, of unprecedentedly increasing the takeout yield of purified hydrogen per unit time without entailing apparatus enlargement and a hydrogen purifier accompanied, even if the thickness of a palladium alloy film is reduced, by scarce mechanical strength losses of hydrogen-permeable capillaries.SOLUTION: The provided hydrogen purifier is a hydrogen purifier of which the interior of a cell is compartmentalized into a primary space and a secondary space by multiple hydrogen-permeable capillaries each having one sealed terminal and a tubular plate supporting the capillaries on the open terminal side of the capillaries, in which a hydrogen gas including impurities is introduced into the primary space and permeated through the capillaries, and in which a purified hydrogen gas is retrieved from the secondary space; the capillary is a metallic pipe having one sealed terminal and possessing multiple holes on its profile plane and is laser-welded with a palladium alloy film wrapped around the profile plane. |
