Zusammenfassung:PROBLEM TO BE SOLVED: To provide a hydrogen-storing tank that is easy to manufacture and allows for quick kinetic absorption of hydrogen, and that has small variations in volume and has a low cost in terms of material and energy.SOLUTION: The hydrogen-storing tank includes a hydrogen inlet (21) and a hydrogen outlet (22) in communication with at least one solid body (10) allowing for exothermal absorption and endothermal desorption of hydrogen. At least one solid body is made of a compacted material containing light metal hydride and a heat-conducting matrix, and at least one solid body is in heat-transfer relation with at least one heat recovery material (42) free from salt or molten salt compounds, and capable of absorbing heat generated by hydrogen absorption and of releasing the absorbed heat so as to provide heat for hydrogen desorption. 【課題】製造が容易であり、素速い動態での水素の吸収を可能にする安全な水素貯蔵タンクであって、体積の変化が小さく、材料およびエネルギーに関して低コストである水素貯蔵タンクを提供する。【解決手段】水素の発熱性の吸収および吸熱性の放出が可能な少なくとも1つの固形物(10)に連通した水素導入部(21)および水素排出部(22)を備えている水素貯蔵タンクであって、前記少なくとも1つの固形物が、軽金属水素化物と熱伝導性のマトリクスとを含む圧縮された材料から製作され、前記少なくとも1つの固形物が、塩または融解塩化合物を含まず、水素の吸収によって生じる熱を吸収でき、かつ前記吸収した熱を水素の放出のための熱を供給するために放出することができる少なくとも1つの熱回収物質(42)との熱伝達の関係にある水素貯蔵タンクとする。【選択図】図6
