Abstract: The present invention discloses a method for forming a catalytic coating. First, at least one alcohol is provided. Then, at least one alcohol and a solvent are mixed to form a middle solution. Next, a heating process is performed to heat the middle solution, and during the heating process, adding a platinum precursor and a protecting agent to the middle solution, so as to form a catalytic coating containing a plurality of platinum nanoparticles with mainly Pt—Pt bond, wherein the protecting agent comprises any one of any combination of the group consisting of: organic acid, polymeric acid, salt of organic acid and salt of polymeric acid. Furthermore, this invention also discloses methods for forming a fuel cell electrode by the mentioned catalytic coating.
