<P>PROBLEM TO BE SOLVED: To provide a hydrogen permeable film excelling in hydrogen permeability at high temperature. <P>SOLUTION: This hydrogen permeable film includes a non-Pd-based alloy layer, and hydrogen permeable layers formed on both surfaces of the non-Pd-based alloy layer, wherein the hydrogen permeable layer is formed of a hydrogen permeable copper alloy consisting of Cu, Pd and Al; and the alloy satisfies a relationship of an expression: [Al]/([Cu]+[Pd])≤(2/9)×[Pd]/([Cu]+[Pd])-(64/9)%, where [Pd]/([Cu]+[Pd])=41-50%, and [Al]/([Cu]+[Pd])=0.05-4.0%, when it is assumed that atomic concentrations (at%) of Cu, Pd and Al are [Cu], [Pd] and [Al], respectively. <P>COPYRIGHT: (C)2013,JPO&INPIT |
