<P>PROBLEM TO BE SOLVED: To prevent temporary change in the temperature of the fuel cell and suppress deterioration of power generating efficiency of the fuel cell even in the case the flow rate of the cooling liquid and the calorific value of the fuel cell are changed. <P>SOLUTION: The fuel cell system comprises a fuel cell, a cooling liquid cooling means for cooling the cooling liquid to cool the fuel cell, and a controller 7 for controlling the cooling system. The controller 7 has a cooling capacity calculating means 27 which calculates the cooling capacity required for the cooling liquid cooling means based on the temperature of the fuel cell, a target cooling liquid flow-rate calculating means 22 for calculating the target cooling liquid flow-rate to be supplied to the fuel cell based on the calorific value of the fuel cell, and a cooling capacity correction means 23 which corrects the cooling capacity required for suppressing the temperature of the fuel cell to be within a prescribed range based on at least one of the target cooling liquid flow-rate and the calorific value of the fuel cell. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
