PROBLEM TO BE SOLVED: To provide a chemical heat storage device capable of suppressing dispersion of heat from a reactor to the outside.SOLUTION: A chemical heat storage device includes a reactor 11, and an adsorber connected to the reactor 11 in such a manner that NHcan flow between the reactor 11 and it so as to store NH. The reactor 11 has a vessel 13 arranged around a heat exchanger 4, a reaction material 14 stored in the vessel 13 and generating heat through a chemical reaction with NHand desorbing NHby heat storage, and a hard heat insulation material 15 disposed between the vessel 13 and the reaction material 14. The hard heat insulation material 15 is formed so that required compression stress at 0.5% compression strain is 0.5 MPa or more and required compression stress at 1% compression strain is 2 MPa or more.SELECTED DRAWING: Figure 3 |
