[en] The hydrogen absorption-desorption performance of the body-centered-cubic (bcc) Ti-V-Cr-Pd alloys have been investigated. Ti₃₃V₃₃Cr₃₄ ingots with 0, 0.05, 0.5 at.% Pd were prepared by arc melting. X-ray diffraction (XRD) revealed that all of these alloys were homogeneous bcc solid solutions. Pd-containing (0.05, 0.5 at.% Pd) Ti-V-Cr alloys have better initial activation properties than those without Pd, and the desorption plateau pressure of the (Ti₃₃V₃₃Cr₃₄)_99.5Pd_0.5 alloy was substantially higher than that of the alloy without Pd. It is also found that the hysteresis difference is smaller in these alloys and degradation of hydrogen absorption capacity becomes steady after the 25th cycling test. (Ti₃₃V₃₃Cr₃₄)_99.5Pd_0.5 alloy exhibits large hydrogen absorption and desorption capacity of up to 3.42 and 2.07 mass% at 353 K, respectively
