METHOD AND PROCESS OF METAL CATALYST FOR FUEL CELL USING A COMPLEX COMPOUND, AND FUEL CELL ELECTRODE ADOPTING THE CATALYST AND FUEL CELL COMPRISING THE ELECTRODE

摘要

The present invention relates to a metal catalyst for a fuel cell using a complex compound and, more particularly, to a method for manufacturing a metal catalyst for a fuel cell comprising the steps of: forming a carbon-based catalyst substrate doped with a chelating agent by mixing a carbon-based catalyst substrate, a chelating agent and a first solvent, adding a reducing agent and thereby conducting primary reduction; forming a transition metal precursor-mixed solution by mixing transition metal precursors in a second solvent; and forming a metal catalyst by dispersing the carbon-based catalyst substrate doped with the chelating agent in the transition metal precursor-mixed solution, adding a reducing agent and thereby conducting secondary reduction. According to the present invention, the electrochemical efficiency of a metal catalyst can be increased while not including platinum or reducing the content thereof and an economical fuel cell can be manufactured by realizing maximal efficiency in the manufacture thereof.
