Abstract
The present invention provides a carrier for a fuel cell including a cryogel-type carbon. A catalyst of the fuel cell includes the cryogel-type carbon and an active material. One of an anode and cathode of the fuel cell has the catalyst including cryogel-type carbon. The carrier for a fuel cell has excellent porosity, specific surface area, and density characteristics, and thus is capable of improving catalyst activity due to excellent catalyst-supporting efficiency, and thereby cell performance.
