<P>PROBLEM TO BE SOLVED: To allow the economical aging to be achieved by performing the excellent aging treatment in a short time, while reducing consumption of hydrogen as much as possible. <P>SOLUTION: The method has a step to feed hot water directly to an electrolyte membrane-electrode structure 20 constituting a fuel cell 10, and an aging step to perform the hydrogen pump operation that the humidified hydrogen permeates a solid polymer electrolyte membrane 14 to be transferred to a cathode side of the fuel cell 10 by feeding the humidified hydrogen to an anode side of the fuel cell 10 without feeding oxidizer gas to the cathode side of the fuel cell 10 while applying the positive pole potential to the anode side of fuel cell 10 and applying the negative pole potential to the cathode side of the fuel cell 10. <P>COPYRIGHT: (C)2009,JPO&INPIT |
