The membrane-electrode assembly for a fuel cell according to an embodiment includes an anode and a cathode facing each other, and a polymer electrolyte membrane interposed therebetween. At least one of the anode and cathode includes an electrode substrate, a microporous layer disposed on the electrode substrate, and a catalyst layer disposed on the microporous layer. The catalyst layer includes a catalyst and a binder resin, and the binder resin has an average chain length ranging from about 5 to about 30 nm. According to the embodiment, a membrane-electrode assembly can be easily prepared without firing and can be prevented from distorting, improving cell characteristics.
