Hydrogen Storage Properties of Ti_(1.2)Fe+xCa Hydrogen Storage Alloys

摘要

The hydrogen storage properties of Ti1,2Fe+xCa （x=1%, 3% and 5% in mass fraction） alloys was Investl- gated. Results show that the modified alloys can be activated without any thermal treatment at room temperatrLre due to the addition of Ca and excess Ti in the alloys. Hydrogen storage properties of these modified alloys vary with Ca amount and reaction temperature. In addition, the influence mechanism of the addition of Ca and excessive Ti on the activation behavior and hydrogen storage capacity of the alloys was discussed.
