PROBLEM TO BE SOLVED: To solve the conventional fuel system's problem of power generation output lowering as a fuel amount is made to reduce in order to lower a fuel cell's temperature.SOLUTION: A fuel cell system 100 comprises: a first air blower 12 for supplying air to a cathode electrode 11a of a fuel cell 11; and an operation controller 31. The operation controller 31 includes: power generation output maintenance means for maintaining power generation output of the fuel cell 11 to be constant; cell deterioration detection means for detecting deterioration of the fuel cell 11; air amount increase means for increasing an amount of air to be supplied to the cathode electrode 11a when deterioration of the fuel cell 11 is detected; air amount increase effect confirmation means for confirming an effect exerted by increasing the amount of air supplied to the cathode electrode 11a; and operation condition setting means for resetting an operation condition for the fuel cell 11. The fuel cell system 100 detects reduction in performance of the fuel cell 11, changes the operation condition of the fuel cell 11, and suppresses the fuel cell 11's temperature being equal to or lower than the upper limit temperature.SELECTED DRAWING: Figure 1 |
