Carbon-based carrier for fuel cell catalyst, catalyst comprising same, membrane-electrode assembly comprising same, and method for preparing same

Abstract

Disclosed are a carbon-based carrier that is capable of increasing catalyst activity as much as that of a porous type while having excellent durability unique to that of a solid type, a catalyst comprising same, a membrane-electrode assembly comprising same, and a method for preparing same. The carbon-based carrier for a fuel cell catalyst of the present invention is a solid-type carrier, and has an outer surface area of 100-450 m2/g, a mesopore volume of 0.25-0.65 cm3/g, and a micropore volume of 0.01-0.05 cm3/g.
