<P>PROBLEM TO BE SOLVED: To make combustion of a combustor in a fuel cell system more stable than before, which is provided with an internal combustor and also is composed so that combustion exhaust gas from the combustor joins combustion exhaust gas from a combustion apparatus. <P>SOLUTION: A fuel cell system comprises a fuel cell unit 1 provided with a fuel cell 13 and a combustor 3, a first exhaust gas passage 4 in which combustion exhaust gas emitted from the combustor 3 flows, and a controller 22. The first exhaust gas passage 4 is connected to a duct having a second exhaust gas passage 6 connected thereto in which combustion exhaust gas flows from a combustion apparatus 5 which generates heat supplied to heat load. The controller 22, when the combustion apparatus 5 and the combustor 3 are both burning, executes an operation to cause either the flow rate of combustible gas supplied to the combustor 3 or the composition of combustible gas to change, thereby exerting control to reduce the output of the combustion apparatus 5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
