FUEL CELL SYSTEM AND METHOD OF STOPPING THE SYSTEM

摘要

When a fuel cell system is to be stopped, a controller 3 decreases the coolant flowrate to a fuel cell 1 , decreases the cooling performance of the fuel cell 1 and continues operation of the fuel cell 1 , and performs a temperature rise operation wherein the temperature of the fuel cell 1 is increased using the heat generated by the electrochemical reaction in the fuel cell 1 . After the temperature of the fuel cell 1 has reached a predetermined high temperature, the operation of the fuel cell 1 is stopped.
