A metal catalyst includes a conductive catalyst material and a proton conductive material coating formed on the surface of the conductive catalyst material. A fuel cell includes an electrode comprising the catalyst. The metal catalyst includes conductive catalyst particles uniformly coated with a proton conductive material to easily form and control a three-phase interface for an electrochemical reaction, facilitate the approach of gaseous reactants to a catalyst through a thin coating of a proton conductive material formed on catalyst particles, and effectively transfer protons produced by the electrochemical reaction. When an electrode is formed using the catalyst, a substantially ideal three-phase interfacial electrode structure may be formed, and a fuel cell including the electrode may have improved performance, such as high efficiency.
