CATALYST FOR FUEL CELL, METHOD FOR PREPARING SAME, AMD MEMBRANE-ELECTRODE ASSEMBLY FOR FUEL CELL COMPRISING SAME

摘要

A catalyst for fuel cell having excellent electric conductivity and catalytic activity, a method for preparing the catalyst, and a membrane-electrode assembly for fuel cell comprising the catalyst are provided. A catalyst for fuel cell comprises: a platinum(Pt) nanowire; and a carbon-based material for supporting the platinum(Pt) nanowire. A method for preparing a catalyst for fuel cell comprises: mixing a carbon-based material with an aspect ratio of 1 or more with a catalytic metal precursor solution comprising a Pt-containing compound to prepare a catalytic precursor; and heat-treating the catalytic precursor. A membrane-electrode assembly for fuel cell comprises: an anode electrode and a cathode electrode formed oppositely to each other; and a polymer electrolyte membrane formed between the anode and cathode electrode, wherein one or both of the anode and cathode electrodes comprise the catalyst for fuel cell comprising a platinum(Pt) nanowire, and a carbon-based material for supporting the platinum(Pt) nanowire.
