Hydrogen production system

A hydrogen production system, comprising:

• a first vessel;
• a second vessel having an internal temperature higher than that of the first vessel;
• a first passage connecting the first vessel and the second vessel;
• and
• a second passage connecting the first vessel and the second vessel and different from the first passage,
• wherein at least one of the first vessel and the second vessel contain a hydrogen compound slurry in which a hydrogen compound member is suspended in a solvent containing water,
• wherein when an element other than hydrogen is defined as X, the hydrogen compound member has a configuration in which a powder containing two-dimensional arrangement of a hydrogen compound represented by a chemical formula XmHn is impregnated on a particulate support, a stoichiometric ratio min is 1:1 to 3:4, and the element X is boron,
• wherein the hydrogen production system further comprising:
• a water supply device for supplying water to the first vessel;
• and
• a hydrogen compound supply device for supplying the hydrogen compound member to the first vessel,
• wherein the hydrogen compound supply device includes:
• a storage for storing the hydrogen compound slurry;
• a slurry supply passage connecting the storage and the first vessel;
• and
• a supply pump, disposed on the slurry supply passage, for supplying the hydrogen compound slurry in the storage to the first vessel, and
• wherein the hydrogen production system is configured to allow the hydrogen compound slurry contained in the first vessel to move into the second vessel through the first passage, and the hydrogen compound slurry contained in the second vessel to move into the first vessel through the second passage.
