<P>PROBLEM TO BE SOLVED: To provide a porous carbon electrode base material with high mechanical strength and surface smoothness, sufficient gas permeability and conductivity, no curling, and capable of suppressing the occurrence of a peel between layers under a load in the direction of the thickness expected in incorporation into a cell. <P>SOLUTION: A manufacturing method of a porous carbon electrode base material comprises steps of manufacturing resin impregnated paper by impregnating paper in which carbon short fibers are dispersed in a two-dimensional plane with a phenol resin, and curing layered two sheets of the resin impregnated paper by hot pressing and carbonizing them. The degree of curing of the phenol resin in the resin impregnated paper before the curing by hot pressing is 5% or lower. <P>COPYRIGHT: (C)2012,JPO&INPIT |
