Zusammenfassung:Provided are a carbon material for a catalyst carrier of a polymer electrolyte fuel cell, the carbon material being a porous carbon material and simultaneously satisfying (1) an intensity ratio (I750/Ipeak) of an intensity at 750 °C (I750) and a peak intensity in a vicinity of 690 °C (Ipeak), in a derivative thermogravimetric curve (DTG) obtained by a thermogravimetric analysis when a temperature is raised at a rate of 10 °C/min under an air atmosphere, is 0.10 or less; (2) a BET specific surface area, determined by BET analysis of a nitrogen gas adsorption isotherm, is from 400 to 1,500 m2/g; (3) an integrated pore volume V2-10 of a pore diameter of from 2 to 10 nm, determined by analysis of the nitrogen gas adsorption isotherm using Dollimore-Heal method, is from 0.4 to 1.5 mL/g; and (4) a nitrogen gas adsorption amount Vmacro at a relative pressure of from 0.95 to 0.99 in the nitrogen gas adsorption isotherm is from 300 to 1,200 cc(STP)/g, as well as a method of producing the same.
