<P>PROBLEM TO BE SOLVED: To solve such a problem that power generation operation cannot be sustained because the entering water temperature to a fuel cell device goes above a predetermined temperature. <P>SOLUTION: A heat exchanger 106 performing sensible heat exchange of the heating medium in a first heat utilization pathway and the outdoor air is additionally disposed on a pathway for supplying the heating medium from a hot-water storage tank 104 to a fuel cell device 100. Since the capacity of a cooling fan 108 of the heat exchanger 106 can be controlled according to the power generation amount, the entering water temperature to a fuel cell device can be lowered surely, and cooling and self-sustenance of water are ensured in the fuel cell power generation section. <P>COPYRIGHT: (C)2013,JPO&INPIT |
