Title:
HYDROGEN STORAGE MATERIAL
Document Type and Number:
Japanese Patent JP2935806
Kind Code:
B2
Abstract:
PURPOSE: To obtain a hydrogen storage material capable of efficiently absorbing and desorbing hydrogen at ordinary temps. and capable of occluding a large amt. of hydrogen.
CONSTITUTION: The material is expressed by Ti100-x-y-zCrxAyBz, where A is ≥1 kind among V, Nb, Mo, Ta and W, B is ≥2 kinds among Zr, Mn, Fe, Co, Ni and Cu, 0<x<70, 0<y<80, 0<z<20 and 0<x+y+z<100. The material has a body-centered cubic structure. The lattice constant (a) of the crystal is limited to conform to 2.95&angst <a<3.10&angst , and the radius of the virtual sphere in contact respectively with two metals at the center of the body of adjacent unit lattices and with two metals at the adjacent corners between the body centers is controlled to ≥0.33&angst . Consequently, a large amt. of hydrogen is occluded at ordianry temps., and hydrogen is economically and practically stored and transported.
