Claim 0:
1. A method of aging a fuel cell, the fuel cell comprising an electrolyte membrane and a pair of electrodes provided on both surfaces of the electrolyte membrane, the method comprising:
performing a first pattern of supplying a humidified hydrogen gas to one electrode of the pair of electrodes and supplying a humidified inert gas to another electrode of the pair of electrodes, to thereby move protons from the one electrode to the other electrode through the electrolyte membrane; and
performing a second pattern of supplying the humidified inert gas to the one electrode and supplying the humidified hydrogen gas to the other electrode, to thereby move protons from the other electrode to the one electrode through the electrolyte membrane,
wherein protons in the electrolyte membrane move in a first direction in the first pattern, protons in the electrolyte membrane move in a second direction in the second pattern, and the first direction and the second direction are opposite to each other.
