The measurement of desorption pressure-composition temperature (P-C-T) behavior of Ti{sub x}Zr{sub 1{minus}x}Ni{sub y}V{sub 2{minus}y} (0 {<=} x {<=} 1,0 {<=} y {<=} 2) has been investigated by means of a 3{sup 2} factorial design method. The response surface function of hydrogen desorption between 0.01 and 10 atm was calculated by Yates` algorithm. Alloy with x=0.35, y=0.60 (i.e. Ti{sub 0.35}Zr{sub 0.65}Ni{sub 0.6}V{sub 0.4}) was found to possess a maximum hydrogen desorption capacity. Finally, the effect of substitution of Mn and Ni for V was also studied. A Ti{sub 0.35}Zr{sub 0.65}Ni{sub 1.2}V{sub 0.4}Mn{sub 0.4} alloy has 1.3871 wt% hydrogen desorption capacity and is a good candidate for an electrode material.
