PROBLEM TO BE SOLVED: To provide a solid oxide type fuel cell device in which a heat exchange amount to a reformer is increased and a temperature of the reformer is speedily elevated.SOLUTION: A solid oxide type fuel cell device comprises: a fuel cell module 2 in which a plurality of fuel cells are accommodated; a combustion chamber which is provided at an upper side of the fuel cells in the fuel cell module and generates fuel gas by combusting residual fuel gas passing through the fuel cells; a reformer 20 which is provided at an upper side of the combustion chamber in the fuel cell module and capable of reforming supplied fuel gas into hydrogen-containing fuel gas; and a heat exchanger 22 which is provided at an upper side of the reformer and performs heat exchange between oxidant gas for power generation and combustion gas in order to heat the oxidant gas for power generation. Between the heat exchanger and the reformer, a heat insulation material is provided which suppresses heat conduction from the combustion gas generated in the combustion chamber to the heat exchanger, and the heat insulation material is formed from one end to another end of the heat exchanger along a bottom face of the heat exchanger. |
