代替タイトル: 有望な磁気熱量効果材料を用いた磁気水素液化システムの評価

説明:

Magnetic refrigeration systems are widely recognized as efficient, compact, and environmentally friendly, given their trivial effect on ozone-depleting or greenhouse gases (e.g., CFCs, HFCs, and HFOs). After the success of liquefying hydrogen by Sir James Dewar in the late 19th century, several liquefaction technologies have been developed. Conventional liquefaction systems involve Joule–Thomson and turbine expansion systems. However, those systems are energy-intensive, which entails about 10–20 kWh/kg for H₂ liquefaction. Magnetic refrigeration systems have recently been employed as a potential alternative to conventional liquefaction systems. Magnetic refrigeration relies on the magnetocaloric effect (MCE), whereby the temperature of a magnetic material changes in response to variations in the magnetic field [1]. This study targets examining different magnetocaloric materials for H₂ liquefaction.
