Patent ID: 8883367

Claim:
A catalyst for a fuel cell, comprising: a carrier other than heat-treated carbon black or activated carbon; and an active metal dispersion supported in the carrier, wherein the active metal has a dispersity (“Dp”) represented by the following General Formula 1 and ranging from about 0.01 to about 1.0: Dp={X−X 10 /( X 1 −B )}×( B/X ) 2 [General Formula 1] wherein X indicates the specific surface area (m 2 /g) of an active metal calculated using the average particle diameter of the active metal acquired from X-ray diffraction spectrum using a CuKα ray and the density thereof, wherein X 10 indicates the specific surface area (m 2 /g) of an active metal calculated using the particle diameter and density of the active metal when it had a particle diameter of 10 nm, wherein X 1 indicates the specific surface area (m 2 /g) of an active metal calculated using the particle diameter and density of the active metal when it had a particle diameter of 1 nm, and wherein B indicates the specific surface area (m 2 /g) of an active metal calculated from the specific surface area of a catalyst for a fuel cell acquired through a BET (Brunauer, Emmett, Teller) analysis.
