Abstract: Disclosed is a membrane-electrode assembly which can prevent the corrosion of a carbon-based carrier caused by reducing and/or stopping the supply of hydrogen gas, as well as platinum loss caused by such corrosion, without degrading the performance of a fuel cell, and thus can improve the reverse voltage durability of the fuel cell. Also disclosed are a method for manufacturing the membrane-electrode assembly, and a fuel cell including the membrane-electrode assembly. The membrane-electrode assembly according to the present invention includes: an electrolyte membrane having a first surface and a second surface opposite the first surface; an anode on the first surface; an OER catalyst layer on the first surface; and a cathode on the second surface, wherein the OER catalyst layer includes a catalyst for an oxygen-generating reaction, and at least a portion of the OER catalyst layer is disposed on the same layer as the anode.
