ABSTRACT:
A material is provided for a polarizable electrode. The material comprises a porous carbon material of activated carbon, activated carbon fibers, carbon fibers or powdery carbon as a raw material, wherein the total amount of acid groups of said porous carbon materials is 0.45 to 4.0 .mu.eq/m.sup.2 based on the BET surface area of said carbon material. The material is produced by subjecting the porous carbon raw material to dry oxidation treatment in an oxygen atmosphere whereby the total amount of acid groups introduced into said porous carbon material is 0.45 to 4.0 .mu.eq/m.sup.2 based on the BET surface area of said material.
