<P>PROBLEM TO BE SOLVED: To improve in an energy-saving property by carrying out appropriate heat storage with due consideration of a volume and time of thermal demand peak. <P>SOLUTION: The fuel cell system is provided with a fuel cell 103 obtaining a power generation output through electrochemical reaction of hydrogen and oxygen, a hot-water tank 109 storing heat recovered from the fuel cell as hot water, a thermal demand volume measurement means measuring a thermal demand volume per unit time, an operating control means 107 controlling power generation, startup, or stoppage of the fuel cell, and an output setting means 106 making output setting based on operation plans of power generation, startup, or stoppage at a plurality of times of the day for the operating control means. The output setting means 106 predicts thermal demand for each of the first given hour in the future with the use of thermal demand for the past given periods measured by the thermal demand volume measurement means, and sets up a power output to be generated from the heat storage volume at a point of time, with a predicted accumulated value of heat demand up to a second given time period calculated based on the predicted thermal demand value as a target thermal storage volume. <P>COPYRIGHT: (C)2010,JPO&INPIT |
