摘要： Disclosed are a membrane-electrode assembly for fuel cells, a method of manufacturing the same and a fuel cell system containing the same. The membrane-electrode assembly for fuel cells includes an anode and a cathode facing each other, and a polymer electrolyte membrane interposed between the anode and the cathode, wherein at least one of the anode and the cathode further includes a porous support and a catalyst layer for fuel cells disposed on one surface of the porous support. The electrode of the membrane-electrode assembly is a free-standing electrode, and the electrode has excellent adhesivity to the polymer electrolyte membrane and thus can prevent performance deterioration resulting from detachment of the electrode from the polymer electrolyte membrane during operation of fuel cells, and in particular, can secure high durability since the electrode is not readily detached even under harsh operation environments.
