%X The hydrogen storage properties and crystal structures of Ti1+xCr1.2Mn0.8(x=0.0, 0.1, 0.2, 0.3) and Ti1+xCr1.2Mn0.8-yMy (M=Fe, Ni, Cu, V, VFe; x=0.0, 0.1; y=0.1, 0.3) have been studied systematically. XRD patterns proved that the two series of hydrogen storage alloys have the same crystal structure, C14(MgZn2) typed Laves phase, which is suitable for hydrogen absorption and desorption with great amount. The lattice parameter a, c and cell volume V increase with increasing Ti content and substitution of Mn by Fe, Ni, Cu, V and VFe, while the hysteresis factors of P-C-T curves decrease. In order to develop hydrogen storage alloys for the metal hydride hydrogen compressor (MHHC), the effect of the substitution elements have been investigated, and the results show that both alloys, TiCr1.2Mn0.5Fe0.3 and Ti1.1Cr1.2Mn0.5Cu0.3, have high hydrogen storage capacities and high compression ratios.
