Abstract

A carbon material for a catalyst carrier of a solid polymer fuel cell, the carbon material including porous activated carbon black satisfying the following requirements: (F) a BET specific surface area (m<2>/g) is from 400 to 1200, (G) Σ<2-6> is from 0.20 to less than 0.70 in a case in which an integrated value of a volume of a pore having a pore size of from 2 to less than to 6 nm is Σ<2-6> in a mesopore distribution, (H) Σ<6-10>/Σ<2-6> is 0.120 to 0.500 in a case in which an integrated value of a volume of a pore having a pore size of from 2 to less than to 6 nm is Σ<2-6> and an integrated value of a volume of a pore having a pore size of from 6 to less than to 10 nm is Σ<6-10> in a mesopore distribution, and (I) I<D>/I<G> is from 1.20 to 2.20 in a case in which an intensity in a D band is I<D> and an intensity in a G band is I<G> in a Raman spectrum.
