Development of Ti-Cr-Mn-Fe based alloys with high hydrogen desorption pressures for hybrid hydrogen storage vessel application

Ti-Cr-Mn-Fe based alloys with high hydrogen desorption plateau pressures have been developed for hybrid hydrogen storage vessel application. Among the studied alloys, Ti1.02Cr1.1Mn0.3Fe0.6 shows the best overall performance for hybrid hydrogen storage. Its hydrogen desorption plateau pressure at 318 K is 41.28 MPa, its hydrogen storage capacity is 1.78 wt.% and its dissociation enthalpy is 16.24 kJ/mol H2.
