| 摘 要： | 储氢合金是有希望成为燃料电池供氢源的方式之一，在各类储氢合金中，以LaNi5为代表的AB5和以TiMn2为代表的AB5发展已较成熟，但由于其储氢量小于2％(质量百分比)而制约了其应用，Mg基合金具有较大的储氢量(3％左右)，但由于其吸放氢条件(温度在473K以上)苛刻难以满足燃料

| Abstract: | The hydrogen storage performance of single BCC phase Ti-V-based alloys was investigated. A hydrogen absorption capacity of 4.2% was achieved at 293 K at a modest pressure(3 MPa) for Ti-40V-10Cr-10Mn alloy. The effective hydrogen capacity of this alloy is 2.6% at 353 K. Moreover, the alloy exhibits a better activation property and flatter hydrogen absorption-desorption plateau. In order to meet different practical application needs, a series of Ti-V-based alloys with various PCT plateau pressures could be obtained by varying the element contents of the alloys, which opened the hope to bring Ti-V-based alloy into reaching the practical application for onboard hydrogen storage systems in fuel cell powered vehicles. |
