<P>PROBLEM TO BE SOLVED: To provide a porous carbon electrode base material in which a carbonized thermosetting resin is bound to carbon short fibers without gaps or cracks and the contents of sodium, potassium, calcium, and iron are significantly low. <P>SOLUTION: A manufacturing method of a porous carbon electrode base material comprises steps of (a) adding a basic aqueous solution to a thermosetting resin solution in which a thermosetting resin containing at least one kind of element selected from the group consisting of sodium, potassium, calcium, and iron is dissolved in a water-soluble organic solvent, agitating, and settling; (b) obtaining a thermosetting resin composition by separating a precipitate from the thermosetting resin solution; (c) obtaining an intermediate base material by impregnating the thermosetting resin composition with a carbon short fiber aggregate in which carbon short fibers are dispersed in a plane; and (d) carbonizing the thermosetting resin composition by heating the intermediate base material. <P>COPYRIGHT: (C)2012,JPO&INPIT |
