PROBLEM TO BE SOLVED: To provide a chemical heat storage device capable of excellently exchanging heat with a heat exchange fluid for heat storage and a heat exchange fluid for heat radiation respectively at heat storage time and heat radiation time while suppressing a decrease in performance of the heat exchange fluids and complexity in flow passage configurations for the heat exchange fluids resulting from flowing of the different heat exchange fluids to a common flow passage.SOLUTION: A chemical heat storage device 100 includes: a reaction vessel 1 including a first heat exchange part 12 in which an exhaust gas flows and a second heat exchange part 13 in which a coolant liquid flows, and a heat storage material storage part 14 which stores a heat storage material 3; and an inversion driving part 2 which moves the reaction vessel 1 selectively to a heat storage position (first position) where the heat storage material 3 comes into contact with the first heat exchange part 12 and a heat radiation position (second position) where the heat storage material 3 comes into contact with the second heat exchange part 13 at the time of heat storage by dehydration reaction of the heat storage material 3 and at the time of heat radiation by hydration reaction. |
