METHOD OF RECOVERING PERFORMANCE OF FUEL CELL STACK

The present disclosure relates to a method of recovering performance of a fuel cell stack in a fuel cell system of a vehicle. The method includes determining whether the fuel cell stack is in a state in which a stack performance recovery operation is possible based on information collected from the vehicle using a predetermined stack state determination criterion, determining whether the vehicle is in a state in which the stack performance recovery operation is possible based on operation information of a fuel cell system, and performing the stack performance recovery operation upon determining that the fuel cell stack is in the state in which the stack performance recovery operation is possible and that the vehicle is in the state in which the stack performance recovery operation is possible.
