PURPOSE:To make it possible to efficiently utilize heat energy generated when chemical energy of a fuel is converted into electric energy by combining together a heat accumulator, a fuel cell device and a heat supply device. CONSTITUTION:While a thermal medium 12 such as water inside a heat accumulator heated by heat energy generated when chemical energy is converted into electric energy, not to speak of electromotive force obtained by a fuel cell 3 is taken out as vapor or hot water, the medium 12 inside the heat accumulator 2 is heated by operating a heater device 19 for storing surplus power as heat energy when required power is sufficed by a part of the power generated by the fuel cell 3, or when the power generated by the fuel cell 3 is not required. Further, when the power exceeding the maximum limit which can be generated by the fuel cell 3 is required, a thermal medium such as methane or ammonium enclosed inside a heater 19 is compress-circulated by a compressor 26 to operate a generator 24 for supplementing power. |
