摘要： To produce a hydrogen storage alloy by melting a hydrogen storage alloy having a body-centered cubic crystal structure without using a refractory crucible and solidifying a molten alloy by a unidirectional solidification process. The unidirectional solidification is carried out by a cold crucible induction melting method at a moving speed of a solid-liquid interface in the range of 10 to 200 mm/hr by using a water-cooled metal crucible in a vacuum or an inert gas atmosphere.

摘要： The invention intends to provide a hydrogen storage alloy that can absorb and release hydrogen effectively at room temperature and shows excellent hydrogen storage amount and effective hydrogen transfer amount and furthermore shows excellent endurance.A pulverized hydrogen storage alloy powder is heated at 600° C. or more and 1200° C. or less for 10 min to 30 hr to apply strain relief annealing. A particle diameter of the hydrogen storage alloy powder is desirably 10 μm or less and the hydrogen storage alloy is desirably mainly composed of a BCC phase. Since the initial strain ahead of the hydrogenation is removed, a solid solution region of hydrogen is largely reduced and an initial hydrogen storage amount and an effective hydrogen transfer amount are increased. Owing to the pulverization, the strains are largely reduced from accumulating and propagating, the strains at the hydrogen storage are largely reduced from generating, an absorption plateau is largely increased, in addition thereto, the deterioration rate due to repetition of hydrogen storage and release can be largely improved.
摘要翻译： 本发明提供一种能够在室温下有效吸收和释放氢的储氢合金，显示出优异的储氢量和有效的氢转移量，并且还显示出优异的耐久性。 将粉碎的储氢合金粉末在600℃以上1200℃以下加热10分钟〜30小时，进行应变消除退火。 储氢合金粉末的粒径优选为10μm以下，希望主要由BCC相组成。 由于氢化之前的初始应变被去除，氢的固溶区域大大降低，并且初始储氢量和有效氢转移量增加。 由于粉碎，菌株在积累和繁殖中大大减少，储氢时的菌株大量减少，吸收平台大大增加，除此之外，由于重复储氢释放而导致的劣化率 大大改善。

摘要： A hydrogen permeable module includes a hydrogen permeable membrane that permeates hydrogen, an outer peripheral part of the hydrogen permeable membrane being restricted, an inside of the outer peripheral part of the hydrogen permeable membrane being not restricted. The hydrogen permeable module permeates the hydrogen by constantly keeping a pressure of a primary side to a pressure that is equal to or more than a pressure of a secondary side. The inside of the outer peripheral part of the hydrogen permeable membrane is not restricted so as to be capable of expanding to the secondary side.

摘要： In a multiphase hydrogen permeation alloy comprising a phase in charge of hydrogen permeation and a phase in charge of hydrogen embrittlement resistance, a structure in which the phase in charge of hydrogen permeability is continuously interconnected and in which more preferably the growth direction of the aforementioned phase in charge of hydrogen permeation lies aligned in the thickness direction of the permeation membrane. As the hydrogen permeation alloy, an Nb—Ti—Co alloy is exemplified, wherein the phase in charge of hydrogen permeability is made of an (Nb, Ti) phase and the aforementioned phase in charge of hydrogen embrittlement resistance is made of a CoTi phase. By virtue of the fact that the growth direction of the phase in charge of hydrogen permeation lies aligned in the thickness direction of the permeation membrane, the hydrogen permeation pass length becomes short to give further improved hydrogen permeation property.
