Abstract
Disclosed is a catalyst, a method for producing the catalyst, an electrode comprising the catalyst, a membrane-electrode assembly comprising the electrode, and a fuel cell comprising the membrane-electrode assembly, the catalyst being highly efficient and having a long service life due to improved interfacial properties with ionomer from having fluoride (F) groups on the surface thereof. The catalyst according to the present invention comprises: a support; metal particles supported in the support; and fluoride (F) groups on the surface of the support and metal particles.
