<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of finishing warming-up in a short time by shortening temperature rising time of a cooling water. <P>SOLUTION: The fuel cell system 1 has a fuel cell 2, a circulation passage 5 which is a flow passage of a cooling liquid to cool the fuel cell 2 and in which the cooing liquid is circulated between a radiator 4 to cool the cooling liquid and the fuel cell 3, a detour route 6 which is the flow passage of the cooling liquid to detour the radiator 4 and in which both ends are connected to the circulation passage 5, and a thermovalve 7 to switch the flow passage of the cooling liquid to either of the flow passage passing through the radiator 4 or the flow passage passing through the detour route 6. Moreover, a weir 8 to adjust a circulation amount by damming a part of the cooling liquid when it is circulated by passing through the detour route 6 is installed at the flow passage of the cooling liquid. <P>COPYRIGHT: (C)2007,JPO&INPIT |
