Patent number: 7842275Abstract: After AlH3 is synthesized, ball milling is performed under a condition in which a force of 2 G to 20 G (G represents the acceleration of gravity) is applied, to thereby provide AlH3 having an X-ray diffraction pattern in the form of a halo pattern. That is, for example, nanostructured AlH3 is provided, in which a grain boundary phase intervenes in a matrix phase, a side length t2 of the matrix phase is not more than 20 nm, and a width w2 of the grain boundary phase is not more than 10 nm. Alternatively, amorphous AlH3 may be provided. Further, hydrogen is released from AlH3 on which ball milling has been completed, and then the hydrogen is absorbed to induce a change into AlHx (provided that 0<x?3 is satisfied). A dopant may also be added. A hydrogen storage container is constructed accommodating the hydrogen absorbing material, which is obtained as described above, inside the container.Type: GrantFiled: December 14, 2007Date of Patent: November 30, 2010Assignee: Honda Motor Co., Ltd.Inventors: Mitsuya Hosoe, Yusuke Sogawa

Patent number: 7037483Abstract: To produce high-pressure hydrogen, water and a hydrogen-generating material (MgH2) which reacts with water to generate hydrogen are weighed so that a target high hydrogen pressure is generated in a high-pressure container. Then, the hydrogen-generating material is introduced into the high-pressure container through its supply port, and water is introduced into the high-pressure container through the supply port. Thereafter, the supply port is closed, thereby causing a reaction between the hydrogen-generating material and the water, so that the hydrogen pressure in the high-pressure container reaches a target high hydrogen pressure.Type: GrantFiled: April 22, 2003Date of Patent: May 2, 2006Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Takanori Suzuki, Izuru Kanoya, Mitsuya Hosoe, Takeaki Isobe
