PURPOSE:To supply hot water of further higher temperature by heat exchanging hot water of prescribed temperature from a hot water generating means, heat exchanging with exhaust gas coming out from a fuel cell generating part, with temperature increasing combustion gas of a fuel cell in a high temperature water generating part. CONSTITUTION:Combustion exhaust gas of heating a reformer 2 and mixed high temperature gas of discharge air or the like discharged from an air pole gas chamber P and cooling gas chamber C of a fuel cell 1 are heat exchanged with clean water in a hot water generating heat exchanger 7, to generate hot water of prescribed temperature. This hot water is stored in a hot water storage tank 8 and used as necessary for a bath 16 and hot water supply 17. In the case of using hot water of further higher temperature, a temperature is set by remote control 15 to supply natural gas to a start up burner 4 burned, and by heat exchanging combustion gas of this burner with hot water of prescribed temperature in a high temperature water generating part, the high temperature water is generated, so that it can be used as reheating or the like of the bath 16. |
