CARBONACEOUS MATERIAL FOR HYDROGEN STORAGE AND METHOD FOR PREPARING THE SAME, AND CELL AND FUEL CELL

摘要

A carbonaceous material for hydrogen storage which stores hydrogen in the fo rm of a proton is provided. Examples of such a carbonaceous material include a carbonaceous material which has a structure having a curvature and has a wor k function greater than 4.9 eV. Such a carbonaceous material can be formed by the arc discharge method. Usable carbonaceous materials for hydrogen storage also include a burned material comprising a polymer of a fullerene, a polyme r of a fullerene through electrolytic polymerization, a derivative based on a carbonaceous material having, introduced into the material, a group capable of bonding with a proton, a carbonaceous material having a structure containing a bending part and a carbonaceous material having, carried thereon, a metal having a catalytic activity for the separation of hydrogen molecules into hydrogen atoms and of hydrogen atoms into protons and electrons. A material for hydrogen storage obtained by applying a plus voltage to a material capab le of storing hydrogen and then subjecting the resultant material to a treatmen t under an atmosphere containing hydrogen is also usable. These materials for hydrogen storage can be used for an electric cell such as a fuel cell, an ai r cell and an alkaline secondary cell.
