摘要: Abstract (Ti0.85Zr0.15)1.1Cr1−xMnFex (x = 0, 0.05, 0.075, 0.1, 0.15) alloys with a C14-type Laves structure have been investigated for potential application in hybrid high-pressure metal hydride tanks used fuel cell vehicles. The effects of the partial substitution Cr Fe on hydrogen storage properties (Ti0.85Zr0.15)1.1CrMn systematically investigated. Results show that desorption plateau pressure increases increasing content alloys, whereas capacity decreases. Among these (Ti0.85Zr0.15)1.1Cr0.925MnFe0.075 has best overall properties, 10.6 atm and reversible 1.54 wt% at 0 °C under range between 0.1 atm 120 atm.
