Abstract: A solid electrolyte type fuel cell power generation system includes a power generation module, an inverter, and a control device. The module includes a stack chamber, a combustion chamber, and a heat exchanging chamber, partitioned one from the other by partition walls, are provided. The stack chamber has a cell stack, an oxidant gas exhaust chamber for collecting an oxidant gas exhausted from the cell stack, and a fuel gas exhaust chamber for collecting a fuel gas exhausted from the cell stack. The oxidant gas exhaust chamber and the fuel gas exhaust chamber are communicated through a first exhaust gas passage provided in the partition wall. In the combustion chamber, the exhaust oxidant and fuel gases which have passed through the first exhaust gas passage are burnt and the resulting combustion gas is introduced into the heat exchanging chamber through the second exhaust gas passage provided in the partition wall.
