Abstract

The hydrogen storage performance of a single body-centered-cubic phase Ti-40V-10Cr-10Mn alloy was investigated. A hydrogen absorption capacity of 4.2 wt.% (H/M = 2.1), which is the highest value at room temperature reported so far, was achieved at 293 K under modest pressure (3 MPa) for this as-cast alloy. The effective hydrogen capacities of this alloy were 2.6, 2.8, and 3.2 wt.%, respectively, at 353, 393, and 523 K, which gave hope of bringing Ti-V-based alloys into the reach of practical application for onboard hydrogen storage systems in fuel cell-powered vehicles.
