摘要：

A hydrogen storage alloy unit comprises a porous body having a large number of holes (spaces) allowing hydrogen atoms to pass through, and a hydrogen storage alloy covering a surface of the porous body inclusive of surfaces of the holes thereof. The hydrogen storage alloy includes a hydrogen storage base formed of a hydrogen storage material, and a catalytic layer covering a surface of the hydrogen storage base. The porous body is formed of an assembly of hydrogen storage fibers formed by vapor-depositing the hydrogen storage alloy onto nanofibers.
