<P>PROBLEM TO BE SOLVED: To enable cooperative control between a cooling system and other heat exchange systems for a fuel cell stack, in the cooling system of a fuel cell. <P>SOLUTION: The cooling system 100 of the fuel cell is provided with a main cooling passage 102 and a branch cooling passage 104, which is arranged in parallel with this and branches the same coolant as a passage in which the coolant flows. A radiator 110 and a circulation pump (WP) 130 or the like are arranged in the main cooling passage 102. The coolant is taken into the branch cooling passage 104 from the main cooling passage 102 and flows to a second heat exchanger 120 through a case or the like of a motor 50 of an ACP (48), and again carries out heat exchange with a passage 80 of the supplied gas, then is returned to the main cooling passage 102. The mode of distribution of the coolant can be changed in various ways, by the mode of the branching of the coolant from the main cooling passage 102 and the arrangement manner of the circulation pump 130. <P>COPYRIGHT: (C)2008,JPO&INPIT |
