<P>PROBLEM TO BE SOLVED: To provide a hydrogen gas release/storage system having improved energy efficiency for releasing/storing hydrogen by reasonably and laconically utilizing the solidification heat of a latent heat storage material which nucreates in a supercool condition to generate solidification heat and the hydrogen storage heat of a hydrogen storage alloy, in a self-contained manner. <P>SOLUTION: The hydrogen gas release/storage unit includes the hydrogen storage alloy 14, the latent heat storage material 16 arranged therearound for nucleating in a supercool condition to generate solidification heat, and a trigger means 24 for cancelling the supercool condition of the latent heat storage material 16. Herein, a closed circulation system includes the process of utilizing the generated solidification heat of the latent heat storage material 16 to heat the hydrogen storage alloy 14 and the process of utilizing the hydrogen storage heat of the hydrogen storage alloy 14 to solve the latent heat storage material 16, in a self-contained manner. <P>COPYRIGHT: (C)2010,JPO&INPIT |
