NOVELTY - The module (12) has a fuel cell stack (24) formed by stacking several fuel cells (22) for generating electricity by electrochemical reactions of fuel gas and oxygen-containing gas. A fuel gas outlet (62b) of a steam reformer (46) is connected to a fuel gas inlet (44a) of the fuel cell stack through a fuel gas channel (66). A fuel gas outlet (61b) of a partial oxidation reformer (45) is connected to a mixed gas inlet (62a) of the steam reformer through a fuel pipe (60c). A water vapor pipe (74b) is connected to a water vapor outlet (73b) of an evaporator (48) merged to the fuel pipe.    USE - Fuel cell module such as solid oxide fuel cell (SOFC) module for use in SOFC fuel cell for generating electricity.    ADVANTAGE - Since the hot reduction gas is supplied from the steam reformer to the fuel gas supply passage of the fuel cell stack through the fuel gas channel, the time required for starting operation of the fuel cell stack is reduced. The water vapor pipe is connected to water vapor outlet of evaporator merged to the fuel pipe, so that the flow of water vapor into the partial oxidation reformer is prevented, thus the steam oxidation of the catalyst in the partial oxidation reformer can be suppressed, and improvement in the durability can be achieved easily.    DETAILED DESCRIPTION - A heat exchanger (50) is provided for raising the temperature of the oxygen-containing gas by heat exchange with the combustion gas, and supplying the oxygen-containing gas to the fuel cell stack. An exhaust gas combustor (52) is provided for combusting the fuel gas and oxygen-containing gas discharged from the fuel cell stack to produce the combustion gas.
