FUEL CELL SYSTEM, FUEL CELL MOUNTABLE VEHICLE AND METHOD OF CONTROLLING FUEL CELL SYSTEM

摘要

A fuel cell system to be mounted on a fuel cell mountable vehicle comprises: a fuel cell; a cooling liquid supply flow path for supplying cooling liquid to the fuel cell; a radiator for cooling the cooling liquid; a first temperature sensor, provided at an outlet of the radiator, for measuring a temperature of the cooling liquid; an ambient temperature sensor; and a controller. The controller executes: estimating a temperature of the cooling liquid inside the cooling liquid supply flow path based on an ambient temperature measured by the ambient temperature sensor; acquiring a temperature of the cooling liquid inside the cooling liquid supply flow path based on the temperature measured by the first temperature sensor after it is determined that the cooling liquid within the radiator has reached the first temperature sensor; and adjusting a flow rate of the cooling liquid based on the estimated temperature or the acquired temperature of the cooling liquid.
