Zusammenfassung:PROBLEM TO BE SOLVED: To provide a solid polymer fuel cell generating device capable of maintaining temperature of cooling water of the fuel cell at a given temperature range without stopping the device even in the case when hot-water storage tank is full of hot water which is not to be supplied outside. SOLUTION: A line is fitted for circulating and sending warm water A to a water tank in free heat exchange heat-exchanged with a heat exchanger coupled with a process gas burner burning hydrogen until stability is reached at starting. When water temperature of the water tank gets above a specified temperature, a fan for sending combustion air to the process gas burner is activated and the heat exchanger is used as a condenser of the warm water A to lower its temperature, and the warm water A lowered in temperature is circulated to the line to cool it down.
