PROBLEM TO BE SOLVED: To provide a solid oxide type fuel cell system including a heat exchanger which inhibits the occurrence of scale in an outflow manifold.SOLUTION: A solid oxide type fuel cell system includes: a fuel cell stack which generates power by oxidation and reduction of a fuel gas and an oxidant; and a heat exchanger 44A for conducting heat exchange between an exhaust gas from the fuel cell stack and water. The heat exchanger 44A includes: a heat exchanger body 72; and multiple partition plates 86A, 88 which are disposed in the heat exchanger body 72 spaced away from each other. The partition plates define multiple first passages 90 in which the exhaust gas from the fuel cell stack flows and multiple second passages 92 where water flows. In regard to an outflow manifold 98, each partition plate is provided with first and second enclosure parts 108, 110 (enclosure means) for enclosing at least part of the outflow manifold 98. |
