<P>PROBLEM TO BE SOLVED: To provide an operation method for recovering an electrolyte film from its deterioration due to dissolution of carbon dioxide in an electrolyte. <P>SOLUTION: The fuel cell system includes an ion control means. In starting an alkaline fuel cell including the electrolyte film 10 and an anode electrode 12 and a cathode electrode 14 as a pair of electrodes disposed on either side of the electrolyte film, the ion control means removes carbonate ions and/or hydrogen carbonate ions and increases hydroxide ions in the electrolyte film. As the ion control means, for example, a means 50 forcibly applying a voltage between the anode electrode 12 and the cathode electrode 14 of the fuel cell is used. <P>COPYRIGHT: (C)2010,JPO&INPIT |
