CARBONACEOUS MATERIAL FOR HYDROGEN STORAGE AND METHOD FOR PREPARATION THEREOF, CARBONACEOUS MATERIAL HAVING HYDROGEN ABSORBED THEREIN AND METHOD FOR PREPARATION THEREOF, CELL AND FUEL CELL USING CARBONACEOUS MATERIAL HAVING HYDROGEN ABSORBED THEREIN

摘要

A carbonaceous material for hydrogen storage which is prepared by subjecting a carbonaceous material to a heat treatment at a temperature of 50°C or higher in a reducing gas atmosphere; a carbonaceous material having hydrogen absorbed therein which is prepared by rendering a carbonaceous material having been subjected to a heat treatment at a temperature of 50°C or higher to absorb hydrogen; and a cell or a fuel cell using the carbonaceous material having hydrogen absorbed therein.
