| 摘要 |
A hydrogen separator (1) exhibits excellent hydrogen separation performance and durability and prevents scattering of an iron-containing substance that causes defects of a selective hydrogen permeable metal membrane (12) in a first passage (7) by covering an iron-containing metal surface (21) that is exposed in the first passage (7) and forms each of a member (9) that forms the first passage (7) and a member disposed in the first passage (7) with an iron component scattering prevention film (31) at least in an area positioned on an upstream side with respect to a downstream end of a permeable section (15) of the selective hydrogen permeable metal membrane (12) in a flow direction of a fluid that flows through the first passage (7).
