| 摘 要： | 研究了Zr0.9Ti0.1V2合金的循环吸放氢性能。合金在吸氢P-C-T曲线的特征区域内具有良好的循环吸氢稳定性，在P-C-T曲线的吸氢平台区（H/A为0.5左右）、吸氢形成氢化物初始阶段（H/A为1~1.2）、吸氢形成氢化物中间阶段（H/A为1.4左右）吸放氢循环测试中，每组循环内合金的吸氢量差别非常小，循环吸氢稳定性很好。经过70次吸氢循环后，合金的吸氢量可以恢复到1.957 (H/A)，合金的粉碎程度很低，表明合金具有良好的循环吸氢能力

| Abstract: | 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 |
