| Outline of Final Research Achievements |
Magnetic refrigerator for hydrogen liquefaction was developed with active magnetic regenerator cycle that is expected to improve thermal efficiency compare with gas expansion. Reciprocating AMR bed could produce large temperature span around hydrogen liquefaction temperature and liquefaction was confirmed using liquid hydrogen level meter for the first time. In order to develop magnetic material for practical use, we studied rare-earth intermettalic compounds. Magnetocarolic effect, thermal conductivity and other properties were measured and evaluated as magnetic refrigerants. Magnetic refrigeration cycles were analyzed with new developed simulation code which takes void gas, thermal conductivity loss and so on.

| Academic Significance and Societal Importance of the Research Achievements |
脱炭素社会のエネルギー源として期待される水素エネルギーの貯蔵、輸送に有利な液体水素を製造する高効率の方式である磁気冷凍法による液化が実証された。特に本研究により、蓄冷型磁気冷凍サイクルによる水素液化に世界で初め成功した。さらに磁性体駆動方式という実用に近い形を用いて実現する大きな成果が得られた。今後、日本が水素エネルギー利用で世界をリードする新しい技術の端緒を開いたという意義がある。
