<P>PROBLEM TO BE SOLVED: To restrain occlusion of a bypass hose in a fuel cell cooling system, through restraint of abrupt pressure fall in the bypass. <P>SOLUTION: The fuel cell cooling system 1 is provided with a radiator 10, a circulation channel 12 through which a coolant is sent from the radiator 10 to a fuel cell 11 and sent back from the fuel cell 11 to the radiator 10, a bypass 13 made of a hose and connecting an upstream side and a downstream side of the radiator 10 between the fuel cell 11 with the radiator 10 in the circulation channel 12, a three-way valve 21 fitted at a connecting part of the bypass 13 and the circulation channel 12 at the downstream side of the radiator 10 and capable of relatively adjusting a volume of the coolant sent from the radiator 10 to the fuel cell 11, the coolant being sent from the bypass 13 to the fuel cell 11, a pump 22 fitted between the three-way valve 21 and the fuel cell 11, and a sub bypass 23 communicating the circulation channel 12 between the pump 22 and the fuel cell 11 with the bypass 13. <P>COPYRIGHT: (C)2010,JPO&INPIT |
