Abstract
Official abstract text for this publication.
In one aspect of the present invention, a hydrogen occlusion body includes: a hydrogen occlusion layer containing a material whose optical property reversibly changes upon hydrogenation and dehydrogenation; and a catalyst layer containing a palladium-ruthenium alloy.
First claim
Opening claim text (preview).
The invention claimed is: 1. A hydrogen occlusion body comprising: a hydrogen occlusion layer containing a material whose optical property reversibly changes upon hydrogenation and dehydrogenation; and a catalyst layer containing a palladium-ruthenium alloy, wherein the palladium-ruthenium alloy is represented by a general formula Pd 1−x Ru x where 0.15<×<0.55. 2. The hydrogen occlusion body according to claim 1 , wherein the material whose optical property reversibly changes is a magnesium-yttrium alloy. 3. The hydrogen occlusion body according to claim 1 , further comprising: a diffusion prevention layer that is provided between the hydrogen occlusion layer and the catalyst layer and that is constituted by a material selected from a group consisting of niobium, vanadium, titanium, or tantalum. 4. The hydrogen occlusion body according to claim 1 , wherein a thickness of the catalyst layer is greater than or equal to 1 nm and less than or equal to 20 nm. 5. The hydrogen occlusion body according to claim 1 , further comprising: a protective layer provided opposite the hydrogen occlusion layer with respect to the catalyst layer. 6. A gasochromic light control element comprising: the hydrogen occlusion body according to claim 1 . 7. A hydrogen sensing element comprising the hydrogen occlusion body according to claim 1 . 8. A hydrogen sensor comprising the hydrogen occlusion body according to claim 1 .
