を得ることができない。 It is known that certain metals and alloys exothermically absorb hydrogen to form metal hydrides, and that these metal hydrides reversibly and endothermically release hydrogen. Various devices have been proposed, such as heat pump devices that utilize the characteristics of metal hydrides. However, in general, a heat pump device is constructed by filling a closed container that also serves as a heat exchanger with metal hydride, and heats the object by exchanging heat with this heat exchanger. In order to obtain high-temperature steam by heating low-temperature steam, the heat transfer coefficient of steam is extremely low, so it is necessary to provide a heat exchanger with many fins. The coefficient of performance of the device decreases, making it impossible to efficiently obtain high-temperature steam.
