Abstract:
1. A method of manufacturing a hydrogen separation membrane, the manufacturing method comprising the steps of: (a) forming an oxidation control layer for controlling oxidation of a hydrogen permeable metal layer on a surface thereof; the oxidation control layer being formed by tungsten, molybdenum, perovskite constituent metal, tungsten trioxide (WO (b) attaching catalytic metal having dissociation and bonding reactions of hydrogen activity in a granular form on a surface of the oxidation control layer, and (c) forming irregularly a surface of the formed oxidation control layer, wherein in the step (a), the oxidation control layer is formed amorphously, in the step (b), the catalytic metal having dissociation and bonding reactions of hydrogen activity is caused to attach in a granular form to a surface of the irregular oxidation control layer, and in the step (c), the surface of the oxidation control layer is formed irregularly by crystallizing the amorphous oxidation control layer.
