Abstract
Disclosed are a catalyst composite for a fuel cell and a method of manufacturing the same. The catalyst composite includes a support containing carbon (C), a metal catalyst supported on the support, and an ionomer binder coated on the surface of the support and on the surface of the metal catalyst. The ionomer binder coated on the surface of the metal catalyst is formed so as to be thinner than the ionomer binder coated on the surface of the support.
