Original Abstract Submitted
A fuel cell system includes a fuel cell stack that generates power by using a reactive gas, and a controller operatively connected to the fuel cell stack and performing a catalyst refresh operation on the fuel cell stack. The controller is configured to determine whether to perform the catalyst refresh operation, by calculating an oxide film amount for the fuel cell stack, to update at least part of parameters used to calculate the oxide film amount based on a state of the fuel cell stack, and to use the updated parameter so as to calculate the oxide film amount.
