FUEL CELL SYSTEM FOR THERMAL MANAGEMENT AND METHOD THEREOF

A fuel cell system includes a sensor device that measures a coolant temperature at an inlet of a fuel cell and an outside-air temperature, a cooling fan that cools a coolant, and a cooling fan controller connected with the sensor device and the cooling fan. The cooling fan controller determines an RPM of the cooling fan, based on the outside-air temperature and an output value of the fuel cell and corrects the RPM of the cooling fan, based on the coolant temperature at the inlet of the fuel cell.
