Abstract:
    A substance occluding material which is high in efficiency, light in weight, low in costs, safe, and high in transportability, and an electrochemical device using it, and a production method for a substance occluding material. A substance occluding material having a substance, e.g. a fullerene molecule (C60), different from a substance to be occluded such as hydrogen gas, contained inside a cylindrical material such as carbon nanotube. A substance occluding material, wherein a cylindrical material such as carbon nanotune or a rod like material such as carbon nanofiber is closely bundled to form a bundle structure, and a material to be occluded such as hydrogen gas is occluded between the cylindrical materials or rod like materials. A substance occluding material, wherein cylindrical materials form a multi-wall structure and a space for occluding a material to be occluded is formed at the innermost of this structure. A production method for a substance occluding material comprising the step of treating the substance occluding material with alkali when the substance occluding material is to be produced. An electrochemical device which uses a hydrogen occluding material as the inventive substance occluding material.
