PURPOSE: To improve the resistance to poisoning by impure gas by coating the surfaces of particles of a hydrogen occluding alloy with thin films of Pd, Cu or Ni permeable selectively to only hydrogen.
CONSTITUTION: The surfaces of particles of a hydrogen occluding alloy represented by formula I (where A is Nb, a rare earth element or the like, k≤0.3, l≤0.3, m≥0.1 and k>m), formula II (where l<1 and k>m in case of l=0.5W0.99), formula III (where D is Zr or V, 0<n≤0.1 and k>n), formula IV, V or VI (where A is Ti, Nb or Mo, 0.4≤x≤1.0, 0≤y≤0.6, k=l+m and 0.2≤k≤0.3), formula VII (where A is Co, Cu or the like, 0.8≤k≤1.4, 0<l<2, 0<m<2, 0<n≤0.2 and 2≤2-l+m+n≤2.2), formula VIII (where 0.5<x<1.5 and 0<y<1) or formula IX (where 0<z<1 and y+z≤1) are coated with thin films of Pd, Cu or Ni to obtain the titled bydrogen occluding and releasing material.
