PROBLEM TO BE SOLVED: To provide a method of manufacturing an electrode material whose base substance is carbon capable of performing oxidation reduction of hydrogen and reduction at noble potential of oxygen with no use of catalyst metal such as platina, and to provide a fuel battery which uses the electrode material manufactured by the method.SOLUTION: A carbon material is processed by ultrasonic radiation in a solution of an arbitrary ratio between hydrophilic organic compound and water. Then, with the carbon material as an electrode, an aqueous solution containing carbamic acid and ethanol is subjected to electrolytic oxidation, and the carbon material, in which a carbon atom on the surface of the carbon material is covalent-bonded to nitrogen-containing functional group and the surface is covalent-bonded to the nitrogen-containing functional group, is subjected to electrolytic reduction treatment in strong acid. And then, it is reacted with sulfuric acid in which sodium nitride is dissolved for diazotation, thereby forming an electrode material whose base substance is the carbon in which diazo group and sulfonic acid group acting as electron suction group are bonded on the surface. An electrode material whose base substance is the above stated carbon is used to constitute a fuel battery. |
