    摘要： A polymer electrolyte fuel cell power generation system comprises: a fuel cell (101) having a plurality of cells each having a polymer electrolyte membrane and an anode and cathode that are formed so as to sandwich the polymer electrolyte membrane therebetween, a fuel gas path formed so as to guide fuel gas from an inlet (403) of the fuel gas to the anode of each cell and discharge the fuel gas to the outside therefrom, an oxidizing gas path formed so as to guide oxidizing gas from an inlet (404) of the oxidizing gas to the cathode of each cell and discharge the oxidizing gas to the outside therefrom, and a cooling fluid path formed so as to guide a cooling fluid from an inlet (401) of the cooling fluid to a cooling fluid supply manifold and then to a region opposite to power generation regions constituted by the anodes and cathodes of the plurality of cells and discharge the cooling fluid to the outside therefrom through an outlet of the cooling fluid, the fuel cell being configured to generate electric power accompanied with heat generation by a reaction between the fuel gas and the oxidizing gas within the power generation regions; a fuel gas supply apparatus (101) for feeding the fuel gas to the inlet of the fuel gas of the fuel cell; an oxidizing gas supply apparatus (103) for feeding the oxidizing gas to the inlet of the oxidizing gas of the fuel cell; a cooling fluid supply system (104) for causing the cooling fluid to flow through the cooling fluid path of the fuel cell, thereby cooling the fuel cell; and a control unit (108), wherein the control unit controls, during the power generation, the temperature of the cooling fluid at the inlet of the cooling fluid though the cooling fluid supply system so as to satisfy T1 ‰§ T2 + 1°C where T1 is a corresponding dew-point temperature of at least either the fuel gas or oxidizing gas at the inlet (403,404) thereof and T2 is the temperature of the cooling fluid at the inlet (401) of the cooling fluid.

    摘要： A method of operating a fuel cell system (10) includes the steps of detecting whether supply of a raw fuel to a fuel cell module (12) is stopped or not, starting supply of water vapor to an electrode surface of an anode based on the temperature of a fuel cell stack (34) when stop of the supply of the raw fuel is detected, starting supply of reverse electrical current to an electrolyte electrode assembly in a direction opposite to electrical current flowing at the time of power generation based on the temperature of the fuel cell stack (34), stopping the supply of the reverse electrical current at least based on any of the temperature of the fuel cell stack (34) and the temperature of an evaporator (38), and stopping the supply of the water vapor at least based on any of the temperature of the fuel cell stack (34) and the temperature of the evaporator (38).

    摘要： An apparatus and method for a normal system shutdown of a SOFC system implements a control strategy that utilizes existing system hardware and operating processes already used during normal operation of the SOFC system. The control strategy enables the SOFC system to generate the fluid needed for prevention of oxidation during the cooling process of the anode side of the SOFC stack by converting the conventional system fuel supply for delivery of a reducing fluid to the anode side of the SOFC stack during normal system shutdown thereby preventing subjecting the hardware to cyclic stress that typically occurs during oxidation. The control strategy further enables the SOFC system to control the temperature gradient that exists across the system hardware thereby eliminating induction of thermal stress on the hardware, hence prolonging the life of the system hardware.
