Title:
CARBON CARRIER FOR FUEL CELL CATALYST AND FUEL CELL CATALYST
Document Type and Number:
WIPO Patent Application WO/2023/090060
Kind Code:
A1
Abstract:
The present invention realizes a carbon carrier for a fuel cell catalyst and a fuel cell catalyst, having excellent durability and catalytic activity when carrying a catalyst metal. A carbon carrier according to one embodiment of the present invention is such that, in the X-ray diffraction spectrum using CuKα rays, diffraction peaks of a (002) plane are observed at at least 2θ = 22.5° to 25°, 26°, and 26.5°, the intensity ratio I(P1)/I(P2) of a peak P1 at 2θ = 26° to a peak P2 at 2θ = 26.5° is 1.4 or more, and the BET specific surface area is 1000 m2/g or more.
