<p>PURPOSE:To improve durability and heat conductivity of a hydrogen storage alloy by mixing fine particles of Cu or Ni with powder of the hydrogen storage alloy and applying Cu or Ni on surface of the hydrogen storage alloy with mechanical strain under drying condition. CONSTITUTION:The fine powder of Cu or Ni having 0.01-3mum average particle diameter is added to the powder of the hydrogen storage alloy having 1-200mum average particle diameter and mixed with the mechanical strain under drying condition by using a mixer of hydridizer, etc., and 30-100%, desirably >=90% of the surface of the hydrogen storage alloy powder is coated with Cu or Ni. Defect, which the hydrogen storage alloy is gradually collapsed to become impossible to use caused by repeating the storage and discharge of the hydrogen or long time for the storage and discharge of the hydrogen is required caused by deterioration of the thermal conductivity, is eliminated.</p> |
