Japanese Patent JP6854685
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a carbon material for a catalyst carrier, which is low in volume density, and suitable for manufacturing a catalyst of a solid polymer fuel cell superior in such characteristics as required in use as a fuel battery; a method for manufacturing the carbon material; and a catalyst carrier for a solid polymer fuel cell, which is arranged by use of the carbon material.SOLUTION: Disclosed are a carbon material for a catalyst carrier of a solid polymer fuel cell and a method for manufacturing the same. The carbon material is a porous carbon material which satisfies all of the following requirements: (1) the volume density is 0.05 g/mL or more and less than 0.14 g/mL; (2) BET specific surface area determined by BET analysis of a nitrogen gas adsorption isotherm is 400-1500 m/g; and (3) a cumulative pore volume Vof a pore size of 2-10 nm determined by analysis of the nitrogen gas adsorption isotherm by Dollimore-Heal method is 0.4-1.5 mL/g.SELECTED DRAWING: None
