Pt-C Pt-TiO2 - CATALYST FOR FEMFC HAVING DOUBLE LAYER STRUCTURE OF Pt-C/Pt-TiO2 AND MEMBRANE ELECTRODE ASSEMBLY COMPRISING THE SAME

摘要

The present invention relates to a catalyst for a polymer electrolyte fuel cell, which comprises a dual structure catalyst for a fuel cell comprising a first catalyst layer composed of Pt-TiO ₂ and a second catalyst layer composed of Pt-C bonded to one surface of the first catalyst layer, to provide. According to the present invention as described above, the double layer catalyst composed of the first catalyst layer of Pt-TiO ₂ and the second catalyst layer of Pt-C is provided to produce water at the anode electrode and improve the storage ability, And enables the operation of the fuel cell in no-humidification.
