<P>PROBLEM TO BE SOLVED: To provide a technique capable of efficiently raising cooling water flowing through a cooling circuit in which a fuel cell is arranged, while keeping stable power generation efficiency of the fuel cell. <P>SOLUTION: A cooling system has a control mode for a flow rate control section including a first flow rate control mode to control a first flow rate that is a flow rate of refrigerant flowing through a cooling circuit in accordance with a power generation state of a fuel cell and a second flow rate control mode which is the second flow rate control mode to control the first flow rate in accordance with a power generation state of the fuel cell, wherein the first flow rate in a given power generation state is smaller in comparison with the first flow rate control mode. When a coupling request for switching from uncoupling state from coupling state is issued, if an outlet water temperature of the fuel cell is lower than the predetermined value, the flow rate control section of the cooling system causes the flow rate control section to perform the operation in the second flow rate control mode. <P>COPYRIGHT: (C)2012,JPO&INPIT |
