The membrane-electrode assembly for a fuel cell includes a polymer electrolyte membrane, and an anode and a cathode disposed on each side of the polymer electrolyte membrane and including a catalyst layer. The catalyst layer has a first catalyst layer that has a porosity of less than or equal to about 40% and is disposed to contact the polymer electrolyte membrane, and a second catalyst layer that has a porosity of more than or equal to about 50% and is disposed on the first catalyst layer.
