Abstract
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 (I/I) of an intensity at 750° C. (I) and a peak intensity in a vicinity of 690° C. (I) is 0.10 or less; (2) a BET specific surface area is from 400 to 1,500 m/g; (3) an integrated pore volume Vof a pore diameter of from 2 to 10 nm is from 0.4 to 1.5 mL/g; and (4) a nitrogen gas adsorption amount Vat 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.
