    • PROBLEM TO BE SOLVED: To solve such a problem that when hydrogen-absorbed borohydride is heated or mixed with water, hydrogen can be released but the use of borohydride is limited since borohydride releases hydrogen at high temperature and further in general hydrogen-released borohydride can not be hydrogenated again and to provide a hydrogen storage material which can release hydrogen at low temperature and the hydrogen-released one of which can be hydrogenated again.
      SOLUTION: A method for forming the hydrogen storage material includes the steps of: preparing a first material of the chemical formula: M(BH
      4 )
      x (wherein M is an alkali metal or an alkaline earth metal); preparing a second material to be selected from M(AlH
      4 )
      x satisfactorily M(AlH
      4 )
      x with MCl
      x , a mixture of MCl
      x with Al, a mixture of MCl
      x with AlH
      3 , a mixture of MH
      x with Al, Al, and AlH
      3 ; and combining the first material with the second material under high hydrogen gas pressure for a while to form a third material having the hydrogen release temperature lower than that of the first material and the hydrogen mass density higher than that of the second material.

    • 解决的问题为了解决当氢吸收的硼氢化合物被加热或与水混合时,可释放氢气,但硼氢化物的使用是有限的,因为硼氢化物在高温下释放氢气, 释放的硼氢化物不能再次氢化并提供可在低温下释放氢的氢储存材料,并且氢释放的氢可以再次被氢化。 解决方案:一种形成储氢材料的方法,包括以下步骤:制备化学式为M(BH 4 )的第一材料(其中M 是碱金属或碱土金属); 从M(AlH SB SB)x SBS xS / SBB中令人满意地制备第二种材料M(AlH 4 SB SB)x SB SBB X MCl x SB,与Al的混合物,MCl x 与AlH SB 3混合物,混合物 具有Al,Al和AlH 3 SB的MH x ; 并在高氢气压力下将第一材料与第二材料组合一段时间,以形成氢释放温度低于第一材料的氢释放温度并且氢质量密度高于第二材料的第三材料。 版权所有(C)2009,JPO&INPIT
