Outline of Research at the Start

本研究では、遍歴電子メタ磁性体が示す一次相転移による巨大磁気熱量効果や圧力熱量効果に着目し、化学圧力を用いてエントロピー特性を最適化した磁性体を開発する。磁化、磁場中比熱、断熱消磁測定などにより磁気熱量効果の評価を行い、磁気冷凍用磁性材料の研究を行う。さらに、実用となる球状磁性体の合成を行うとともに、試験冷凍機での実証評価を行い、高性能な水素液化磁気冷凍の研究開発を進める。

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. Rotational type magnetic refrigerator was tested also. We studied rare-earth intermetallic compounds. Magnetocarolic effect, thermal conductivity and resistivity were measured in magnetic fields and evaluated as magnetic refrigerants in terms of transport properites. 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。特に本研究グループにより、蓄冷型磁気冷凍サイクルを用いた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。本研究では、磁性体の輸送特性の観点からも物性解明が進められ、サイクルシミュレーションと共に、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。
