Abstract:
1. A fuel cell module comprising: a fuel cell stack formed by stacking a plurality of fuel cells for generating electricity by electrochemical reactions of a fuel gas and an oxygen-containing gas; a partial oxidation reformer for reforming a mixed gas of a raw fuel chiefly containing hydrocarbon and an oxygen-containing gas; a steam reformer for reforming a mixed gas of the raw fuel and water vapor; an evaporator for evaporating water and supplying water vapor to the steam reformer; a heat exchanger for raising the temperature of the oxygen-containing gas by heat exchange with a combustion gas, and supplying the oxygen-containing gas to the fuel cell stack; and an exhaust gas combustor for combusting the fuel gas discharged from the fuel cell stack as a fuel exhaust gas and the oxygen-containing gas discharged from the fuel cell stack as an oxygen-containing exhaust gas to produce the combustion gas; wherein a fuel gas outlet of the steam reformer is connected to a fuel gas inlet of the fuel cell stack through a fuel gas channel; a fuel gas outlet of the partial oxidation reformer is connected to a mixed gas inlet of the steam reformer through a fuel pipe, and a water vapor pipe connected to a water vapor outlet of the evaporator is merged to the fuel pipe; the exhaust gas combustor is housed inside a first chamber that houses the heat exchanger, and the steam reformer is housed inside a second chamber, the first chamber and the second chamber being separate members that are fixed to one other.
