CARBON-BASED CARRIER FOR FUEL CELL CATALYST, CATALYST COMPRISING SAME, MEMBRANE-ELECTRODE ASSEMBLY COMPRISING SAME, AND METHOD FOR PREPARING SAME

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 m/g, a mesopore volume of 0.25-0.65 cm/g, and a micropore volume of 0.01-0.05 cm/g.
