Hydrogen storage unit

Absorbing porous body 7 is hydrogen atom with a number of holes (clearance) 9 can pass, and a hydrogen storage alloy covering the surface of the porous body 7 including the hole, the hydrogen storage alloy, the hydrogen It has a hydrogen-absorbing base formed of a material that, a catalyst layer covering the hydrogen storage-based surface. Porous body 7 is an aggregate of the hydrogen storage fibers 8 is deposited a hydrogen storage alloy nanofibers.
