Abstract
The present invention relates to a method for manufacturing a porous electrode base material including the following steps [1] to [3]: [1] a step for dispersing short carbon fibers (A) to form a sheet-form product; [2] a step for adding, to the sheet-form product, at least one phenolic resin (c) selected from a group consisting of a water soluble phenolic resin and a water dispersible phenolic resin along with carbon powder (d) to form a precursor sheet; and [3] a step for carbonizing the precursor sheet at the temperature of 1000° C. or higher, after the step [2].
