[en] 'Full text:' Body - centered cubic (BCC) alloys, like the Ti-Cr-V system, have been investigated extensively because of their high hydrogen storage capacity. It has been reported that the Ti-V-Cr alloy exhibits a large hydrogen storage capacity of 2.8 mass%. This value of capacity seems to be acceptable for hydrogen storage tanks used on-board vehicles. However, despite the good results achieved by Ti-Cr-V alloys, the high cost of pure V used as raw material for the synthesis of these alloys is disadvantageous for practical applications. In this work, the expensive pure V metal was replaced for a quite cheap ferrovanadium (FeV) commercial alloy. Alloys with the composition TiCr_2x(FeV)_x were synthesized and investigated. For some compositions, the pressure-composition-temperature (PCT) isotherms at 323 K showed that the effective hydrogen storage capacity could reach around 2.0 wt%. The main advantages of this class of alloys over the conventional LaNi₅ alloy, which has been massively applied to Ni-MH rechargeable batteries, are its larger hydrogen storage capacity and lower costs.
