<P>PROBLEM TO BE SOLVED: To maintain balance between power generating output and use of exhaust heat, to efficiently execute operation of a fuel cell system by evading a state of excess heat as much as possible and to downsize the system as a whole by downsizing a cooling means of the fuel cell system. <P>SOLUTION: The fuel cell system derives a power generating output limit value EL (first power generating output limit value deriving means) based on hot water storage tank exit temperature T4 detected by a fourth temperature sensor 72a and a first map or an operational expression indicating a relative relationship between the hot water storage tank exit temperature T4 and the power generating output limit value EL for the fuel cell in step 104. In steps 106 to 114, power generating output for the fuel cell is controlled based on the power generating output limit value EL derived by the first power generating output limit value deriving means (first power generating control means). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
