METHOD FOR CONTROLLING FUEL CELL SYSTEM

PROBLEM TO BE SOLVED: To quickly reduce an oxidized anode electrode and to restrain deterioration of a membrane-electrode assembly as much as possible. SOLUTION: A method for controlling the fuel cell system includes: a first step of setting a target output value Wt+1 of a fuel cell stack; a second step of detecting a present output value Wt of the fuel cell stack; a third step of comparing the target output value Wt+1 with the present output value Wt; a fourth step of supplying fuel gas to the fuel cell stack in response to the target output value Wt+1; a fifth step of detecting at least either resistance change or voltage change of the fuel cell stack; a sixth step of comparing either of at least the resistance change and a set value of the preset resistance change, or the voltage change and a set value of the preset voltage change; and a seventh step of setting the present output value Wt of the fuel cell stack as the target output value Wt+1.
