Abstract
Description
請求項2の発明では、請求項1の発明において、前記触媒層は、Pdで形成されていることを特徴としている。
請求項5の発明では、請求項3の発明において、前記多孔質体は、ナノファイバの集合体であることを特徴としている。
請求項7の発明では、請求項3の発明において、前記水素吸蔵合金の前記水素吸蔵ベースは前記多孔質体の前記表面に蒸着によって層状に形成されていることを特徴としている。
図示したように、本発明に係る水素吸蔵合金1は、水素吸蔵ベース2と、触媒層3からなる。水素吸蔵ベース2は、Mg金属4と、他の合金(図ではMg2Ni5)とを混合して薄膜化したものである。このMg4とMg2Ni5の混合割合は、1分子のMg2Niに対し、0〜10(0を含まない)分子のMgである。より好ましくは、1分子のMg2Niに対し、4〜8分子のMgである。特に、混合後の化学式がMg6Niであることが好ましい。このようにMg4とMg2Ni5とを混合することにより、以下の化学反応がおこり、図の矢印で示すように、水素原子Hが内側のMg(又はMg2Ni)に渡され、水素の固体拡散性能が高まる。したがって、迅速な水素吸蔵を実現できる。なお、水素吸蔵ベース2は、アモルファス状態であることが好ましい。また、水素吸蔵ベース2を薄膜化したことも水素吸蔵の迅速化に寄与している。
Mg2Ni+4H2→Mg2NiH4
図示したように、本発明に係る水素吸蔵ユニット7は、ナノファイバに水素吸蔵合金1(図1参照)が蒸着した水素吸蔵繊維8の集合体である。水素吸蔵繊維8が多数交差することにより、隙間9が形成される。個々のナノファイバの向きはランダムでよい。この隙間9の大きさは、水素分子が通過可能な大きさに形成されている。このようなナノファイバに水素吸蔵合金1(図1参照)が蒸着されているので、水素吸蔵ベース2(図1参照)の表面積が大きくなり、水素との接触面積が広がる。すなわち、隙間9が水素分子を通過させる孔となって、水素吸蔵ユニット7の表面だけではなく、水素吸蔵ユニット7の内側まで入り込んでから水素が吸蔵されるため、より迅速な水素吸蔵を実現することができる。
図示したように、水素吸蔵繊維8は、ナノファイバ10と、水素吸蔵ベース(水素吸蔵層)2と、触媒層3で形成されている。より詳しくは、ナノファイバ10の表面に水素吸蔵合金1が層状に蒸着されて形成されている。このような水素吸蔵繊維8が多数交差して絡み合って集合体となることで、水素吸蔵ユニット7を形成している。ナノファイバ10の表面が平滑である場合、図のように均一に蒸着される。ナノファイバは、エレクトロスピニング法等を用いて作成することができる。
図示したように、水素吸蔵合金1がナノ合金粒子となった場合、MgとMg2Niからなる水素吸蔵ベース(水素吸蔵コア)2が球状となり、その周りをPdからなる触媒層3が球状となって覆う。すなわち、水素吸蔵コア2と触媒層3でコロイドを形成している。このようなナノ合金粒子が、ナノファイバ10の周囲に付着して水素吸蔵繊維8が形成される。
グラフに示されるように、真空状態で水素を供給すると、水素吸蔵合金による水素吸蔵が開始されつつ圧力が増加していく。時間Tで水素の供給を止めると、水素吸蔵合金による水素吸蔵がさらに進み、圧力が一気に低下している。圧力の低下は、供給された気体水素の圧力の低下を示し、水素が吸蔵されていることを示している。したがって、迅速な水素吸蔵が行われていることが確認できる。
