Title:

HYDROGEN SEPARATION MEMBRANE AND HYDROGEN-SEPARATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2012/121275

Kind Code:

A1

Abstract:

Provided are a hydrogen separation membrane having exceptional resistance to extrinsic airborne particles, and a hydrogen-separation device having this hydrogen separation membrane. A hydrogen separation membrane provided with a surface catalyst layer comprising a Pd alloy or having a surface comprising a Pd alloy, wherein the hydrogen separation membrane is characterized in that the Pd alloy contains 0.01 to 10 mol% of at least one metal from group 5A and/or group 6A. A hydrogen-separation device having this hydrogen separation membrane is also provided. The metal is preferably at least one of V, Nb, Ta, Cr, Mo, or W. The present invention prevents the occurrence of Kirkendall voids regardless of the adherence of extrinsic airborne particles.
