Hydrogen separation membrane, hydrogen separation unit, and manufacturing method for hydrogen separation membrane |
摘要 |
<p>There is provided a hydrogen separation membrane capable of providing high hydrogen permeability and accommodating an increase in pressure difference, a hydrogen separation unit, and a manufacturing method for a hydrogen separation membrane. The hydrogen separation unit 1 has a hydrogen separation membrane 10 and a metallic porous support sheet 20 attached to the hydrogen separation membrane 10. By forming a plurality of pits in the surface of the hydrogen separation membrane 10, a thick-wall portion 15 having a large thickness and a thin-wall portion 16 having a small thickness are provided on the hydrogen separation membrane 10. Also, as a method for forming pits i.e. thin-wall portions 16, etching process is used. <IMAGE></p> |
