<P>PROBLEM TO BE SOLVED: To provide a cogeneration system that can be favorably applied to a system whose exhaust heat collection amount is comparatively small by efficiently collecting exhaust heat. <P>SOLUTION: The cogeneration system includes a reformer 6 for reforming raw fuel gas, a solid oxide fuel cell 2 including a fuel cell stack 8 for generating power by oxidation and reduction between a reformed fuel gas reformed by the reformer 6 and an oxidant and a blower 10 for feeding the oxidant to the fuel cell stack 8, a hot water storage apparatus 4 for collecting exhaust heat from the solid oxide fuel cell 2 as hot water, and a control means for controlling these units. When a storage amount of hot water in a hot water storage tank 52 of the hot water storage apparatus 4 is small, the control means drives the hot water storage apparatus 4 in a low temperature heat collection mode, and when the storage amount of hot water in the hot water storage tank 52, the control means drives the hot water storage apparatus 4 in a high temperature heat collection mode. <P>COPYRIGHT: (C)2013,JPO&INPIT |
