PURPOSE:To control the discrepancy between an electric-power load pattern and a hot- water-supply load pattern by temporarily storing heat generated in a fuel cell so as to absorb the variation of the generated heat which accompanies the load variation of a fuel cell, and warming supply water with the accumulated heat. CONSTITUTION:A fuel such as naphtha or methane, and steam used for reformation are supplied from 92 and 114 and sent into the reaction chamber 32 of a reformer 30. In a shift converter 40, carbon monoxide produced in the reformer 30 reacts with steam to be converted into hydrogen and carbon dioxide gas, which are supplied through 95 into the anodic chamber 15 of a fuel cell 10. On the other hand, air is compressed to a given pressure by means of a compressor 21, and supplied through 81 into the cathodic chamber 11 of the fuel cell 10. In the fuel call 10, voltage develops between a cathode 12 and an anode 14 due to electrochemical reaction, and electric power is released through electric-power lines 71. Since the the temperature of the fuel cell 10 tends to increase due to Joule heat, which develops in the cell 10 when a current is fed to the cell 10 by connecting a load to the cell 10, the heat of the cell 10 is taken out and delivered into a regenerator container 50 by supplying a heat medium 121 into a cooling part 16. |
