The effect of Ti content on the hydrogen storage properties of ZrTiMn Ce ( x = 0, 0.2, 0.3, 0.5) alloys was studied by X-ray diffraction, scanning electron microscopy and pressure-composition ( p-c) isotherm measurement. All of the alloys mainly consist of C14-type Laves and CeO2 phases. As the Ti content increases, the lattice parameters of the Laves phase decrease and the unit cell shrinks anisotropically, the total hydrogen absorption capacity decreases but the reversible hydrogen desorption capacity of the alloys increases, and the equilibrium pressure of the alloys increases but the plateau becomes sloping. The changes of hydrogen storage properties of ZrTiMn Ce alloys are related to the differences in both atomic radius and hydrogen affinity between Ti and Zr elements. [ABSTRACT FROM AUTHOR]
