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.

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

Disclosed are a radical scavenger, a method for preparing same, and a membrane-electrode assembly containing same, wherein the radical scavenger can maintain the performance of a fuel cell for a long time and enhance the lifespan thereof since the elution of metal ions derived from radical scavenging particles during fuel cell operation can be continuously prevented for a long time. The radical scavenger of the present invention comprises: radical scavenging particles; and a porous protective film on the surface of the radical scavenging particles, wherein the porous protective film comprises at least one material of high oxidative stability selected from the group consisting of silica, carbon nitride, heteroatom-doped graphene, a porphyrin-based compound, a phenazine-based compound, and derivatives thereof.
