In this study, a series of quaternary TiFe-based alloys, Ti1.05Fe0.85Cr0.1−xMox (x = 0, 0.03, 0.05, 0.07, 0.1), were designed to investigate the activation and hydrogen ab-/desorption properties TiFe storage alloys through substitution Fe with Cr Mo. The incorporation Mo significantly enhanced performance enabling at room temperature. This improvement in was accompanied by maintenance high maximum capacity an elevated effective capacity. As content increased, lattice parameters increased slightly, further boosting reducing optimal operating temperature from 90 75 °C, which can be readily matched using waste heat fuel cells. addition also resulted flatter absorption plateau, making release process more stable. Among Ti1.05Fe0.85Cr0.05Mo0.05 exhibited best performance, 2.00 wt.%, 1.81 relatively flat plateau. After 200 cycles, decreased only 0.50%, indicating promising application prospects related fields.
