Carbonaceous material, hydrogenoccluding material, hydrogen-occluding apparatus, fuel cell, and method of hydrogen occlusion

摘要

The present invention relates to a carbonaceous material including a cylindrical carbonaceous molecule; and an atom or atomic group introduced thereinto, wherein a chemical potential of a hydrogen molecule near the cylindrical carbonaceous molecule introduced the atom or atomic group thereinto is lower than a chemical potential of another hydrogen molecule near a cylindrical carbonaceous molecule which is not introduced the atom or atomic group thereinto, the position of the latter hydrogen molecule being equivalent to that of the former hydrogen molecule to the cylindrical carbonaceous molecule. With this configuration, it is possible to realize greatly improved hydrogen-occluding performance (or capability of occluding a large amount of hydrogen under normal pressure).
