HYDROGEN-STORAGE MATERIAL CONTAINER CONSTITUTED OF TITANIUM

WIPO Patent Application WO/2011/102435

A1

A hydrogen-storage material container constituted of titanium is provided in which hydrogen embrittlement accompanying the occlusion/release of hydrogen can be prevented. The hydrogen-storage material container constituted of titanium is for containing a hydrogen-storage material (hydrogen-storage alloy powder (5)) and comprises: a container main body (1) constituted of titanium; and partitions (a side wall plate 2 and a bottom plate 3) which are located on the inner side of the container main body (1) constituted of titanium and are interposed between the container main body (1) constituted of titanium and the hydrogen-storage material without being areally bonded to the container main body (1) constituted of titanium and which prevent the hydrogen-storage material from coming into contact with the container main body (1) constituted of titanium. In the container, hydrogen atoms generated by the catalytic effect of the hydrogen-storage alloy powder (5) during hydrogen occlusion/release are prevented from reaching to the surface of the container main body (1) constituted of titanium and penetrating into the container main body (1) constituted of titanium, and the container main body constituted of titanium is inhibited from suffering hydrogen embrittlement.
