  • Patent number: 7037622
    Abstract: A hydrogen-storing carbonaceous material is provided. The hydrogen-storing carbonaceous material is obtained by heating a carbonaceous material at lower than about 800° C. before hydrogen is stored under the pressure of hydrogen of about 50 atmospheric pressure or higher. The present invention also provides hydrogen-stored carbonaceous material that is obtained by hydrogen storage in the hydrogen-storing carbonaceous material under the pressure of hydrogen of about 50 atmospheric pressure or higher. This hydrogen-stored carbonaceous material is used for a battery or a fuel cell. The hydrogen-stored carbonaceous material is heated at lower than about 800° C. before the hydrogen is stored under the pressure of hydrogen of about 50 atmospheric pressure or higher, so that the hydrogen-storing carbonaceous material whose hydrogen storage capacity is greatly enhanced can be produced.

  • Patent number: 7014952
    Abstract: A hydrogen-storing carbonaceous material is provided. The hydrogen-storing carbonaceous material is obtained by heating a carbonaceous material in a gas atmosphere including hydrogen gas and substantially including no reactive gas as impurity gas to store hydrogen. According to the present invention, since the surface of the carbonaceous material can be cleaned and hydrogen can be stored in the carbonaceous material in the same gas atmosphere and a hydrogen-stored carbonaceous material can be produced by controlling a heating process time in the gas atmosphere including the hydrogen gas and substantially including no reactive gas as the impurity gas. This can facilitate the use of the hydrogen-stored carbonaceous material as applied to devices, systems, processes and/or the like.

  • Patent number: 7014951
    Abstract: A hydrogen-stored carbonaceous material is provided. The present invention relates to a hydrogen-stored carbonaceous material obtained by storing hydrogen in a carbonaceous material heated at more than about 230° C. under pressure in a reducing atmosphere, a battery and a fuel cell using same. The carbonaceous material is heated at more than about 230° C. under pressure in a reducing atmosphere so that its surface can be efficiently cleaned and an area where the surface of the carbonaceous material comes into contact with hydrogen atoms or hydrogen molecules is increased.
