Abstract
Embodiments of the present invention relate to non-noble metal-based catalysts used as electrode materials for fuel cells, and methods of manufacturing the same.In an aspect of the present inventions, provided herein is a non-noble metal-based catalyst for an electrode of a fuel cell. The non-noble metal-based catalyst comprise a porous carbon having a first pore and a second pore smaller than the first pore. The first pore has a pore size of about 5 to 100 nm and has an inner wall into which an active site of the non-noble metal-based catalyst is introduced.
