摘要： A hydrogen supply method includes a two-side heat exchange mode in which both introducing a second fluid into a hydrogen storage part after the second fluid exchanges heat with a first fluid in a second heat exchanger in a state in which a compressor is driven to compress the first fluid and introducing the second fluid into the hydrogen storage part after the second fluid is heated or cooled in a thermal device are performed. The method also includes a one-side heat exchange mode in which one of introducing the second fluid into the hydrogen storage part after the second fluid exchanges heat with the first fluid in the second heat exchanger in a state in which the compressor is driven to compress the first fluid and introducing the second fluid into the hydrogen storage part after the second fluid is heated or cooled in the thermal device is performed.

摘要： A hydrogen storage device includes a storage container having an accommodation space in an interior thereof, a first metal hydride material provided in the interior of the storage container and that stores hydrogen, and a second metal hydride material provided in the interior of the storage container and that stores the hydrogen at a pressure that is different from that of the first metal hydride material. An advantageous effect of restraining an excessive rise of a pressure of the storage container and enhancing safety and reliability may be obtained.
