Claim 0:
1. A method of manufacturing a fuel cell, comprising:
bonding a sub-gasket, provided with an air inlet and a hydrogen inlet, to a side surface of a three-layer membrane-electrode assembly (MEA) including an electrolyte membrane, a cathode located on one surface of the electrolyte membrane, and an anode located on the other surface of the electrolyte membrane;
stacking a gas diffusion layer on the cathode and the anode of the three-layer membrane-electrode assembly to obtain a five-layer MEA, wherein at least one of the gas diffusion layers comprises an antioxidant precursor;
and
applying a current to the five-layer MEA and moving an antioxidant, which is derived from the antioxidant precursor, to the electrolyte membrane.
