<p>PROBLEM TO BE SOLVED: To produce a hydrogen storage alloy body capable of reducing the stress occurring in a hydrogen storage alloy vessel by reducing the friction among powder grains of a hydrogen storage alloy. SOLUTION: A hydrogen storage alloy body 110 is formed by aggregating hydrogen storage alloy grains 110A, and a lubricating material 120 is interposed among these hydrogen storage alloy grains 110A. By this method, the friction among the hydrogen storage alloy grains 110A can be reduced. At this time, alkylnaphthalene is preferably used as the principal component of the lubricating material.</p> |
