PURPOSE:To prevent carbon precipitation by controlling the temperature of an anode inlet at high level in partial load. CONSTITUTION:A bypass line 24 is provided in which a reformed material gas is guided to the reforming chamber 4a of a reformer 4 by bypassing a reformed material gas preheater 8. The bypass flow of the reformed material gas is controlled by a flow control valve 25 adjusted by the temperature of the reformed gas on the side of an anode 3 inlet. When the flow of the reformed material gas of a reformed material gas feeding line 5 is to be controlled, the amount of steam is controlled by a flow controller 29 above a steam line 7 so that S/C becomes higher by the signal from a flow controller 27, at the same time, and the S/C is increased and no thermal decomposition of methane occurs. |
