摘要：
The hydrogenation/dehydrogenation processes of Zr0.9Ti0.1V2 hydrogen storage alloy were investigated by cyclic hydriding-dehydriding tests. Reversible hydrogen absorption properties were studied in three characteristic domains on P-C-T curves. Hydrogen contents is similar during each cyclic hydriding-dehydriding test including the hydrogen absorption plateau stage (0.5 H/A), the initial stage of the hydride formation (1-1.2 H/A) and the mid stage of the hydride formation (1.4 H/A). After 70 hydrogenation/dehydrogenation cycles, the regeneration hydrogen absorption capacities could reach to as large as 1.957 (H/A). The experimental Zr0.9Ti0.1V2 alloy exhibits excellent cyclic hydrogenation properties.
