<P>PROBLEM TO BE SOLVED: To provide a technique capable of eliminating degradation in a fuel cell, after stopping power generation. <P>SOLUTION: A fuel-cell system 10 is equipped with a supply-stopping unit 912 for stopping supply of hydrogen to an anode electrode 243 and the supply of air to a cathode electrode 247, when the power generation by the fuel cell 20 is stopped; a voltage-measuring unit 914 for measure a cell voltage, representing the voltage difference between the anode electrode 243 and the cathode electrode 247; and an air inlet portion 916 for introducing air into the anode electrode 243, after stopping the supply of the air and the hydrogen by the supply-stopping unit 912, when the cell voltage measured by the voltage-measuring unit 914 drops below a reference voltage. <P>COPYRIGHT: (C)2011,JPO&INPIT |
