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.
