PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell system capable of suppressing the high-temperature air pooled in the upper end part of a second passage where water flows.SOLUTION: A heat exchanger 44 is provided with its heat exchanger body 72 and a plurality of partition plates 86, 88 arranged at an interval in the heat exchanger body 72. The plurality of partition plates 86, 88 define alternately a plurality of first passages 90 and a second passages 92. An inflow manifold 102 which is communicated with each upstream side of the plurality of second passages 92 is installed at the lower end part of the heat exchanger body 72, and an outflow manifold 98, which is communicated with each downstream side of the plurality of second passages 92 is installed at the upper end part. The inflow manifold 102 and the outflow manifold 98 are installed penetrating the plurality of first passages 90 and the second passages 92 in the arrangement direction of the plurality of the partition plates. Each of upper end parts of the plurality of second passages 92 is inclined at an upward gradient, in the flowing direction of water and toward the outflow manifold 98.
