MEMBRANE ELECTRODE ASSEMBLY FOR FUEL CELL, METHOD FOR PREPARING SAME, AND FUEL CELL SYSTEM COMPRISING SAME

A membrane-electrode assembly for a fuel cell is provided to ensure excellent cell power with a reduced loading amount of a catalyst, and to improve electronic conductivity within the fuel cell. A membrane-electrode assembly for a fuel cell includes an anode electrode and a cathode electrode placed to face each other, and a polymer electrolyte membrane placed between the anode electrode and cathode electrode. At least one electrode of the anode and cathode electrodes has an electrode substrate and a catalyst layer(110) formed on the electrode substrate. The catalyst layer includes a catalytic part(110a) comprising a catalyst, and a conductive part(110b) comprising a conductive material.
