Abstract
Disclosed is a method of thermal management of a fuel cell system capable of estimating the temperature of a membrane electrode assembly (MEA) of a fuel cell stack based on data that can be collected in real time and performing thermal management of the fuel cell stack based on the estimated temperature of the MEA, the method including determining, by a controller, a heating value and thermal resistance of a fuel cell stack during driving of a vehicle, estimating the temperature of an MEA provided to the fuel cell stack based on the heating value and the thermal resistance of the fuel cell stack, and performing thermal management of the fuel cell stack based on the estimated temperature of the MEA.
