<P>PROBLEM TO BE SOLVED: To provide a fuel battery system capable of improving layout properties of a flow channel for leading a refrigerant to a heat exchanger, and capable of effectively warming the heat exchanger. <P>SOLUTION: A cooling mechanism 12 is provided with a refrigerant supply flow channel 47 connected to a front end side of a fuel cell stack 11 and leading the refrigerant into the fuel cell stack 11, a refrigerant discharge flow channel 52 leading out the refrigerant from the fuel cell stack 11, a refrigerant flow channel communicating between the refrigerant supply flow channel 47 and the refrigerant discharge flow channel 52 in the fuel cell stack 11, and a refrigerant bypass channel 55 fitted by branching from the refrigerant flow channel between the refrigerant supply flow channel 47 and the refrigerant discharge flow channel 52, and leading the refrigerant to a rear end side of the fuel cell stack 11 through flowing in that 11. A heat exchanger 31 is arranged at rear side of the fuel cell stack 11, and the refrigerant is lead from the refrigerant bypass channel 55 into the heat exchanger 31. <P>COPYRIGHT: (C)2010,JPO&INPIT |
