<P>PROBLEM TO BE SOLVED: To provide an operation method of a fuel cell power generation system capable of exerting an excellent voltage drop suppression effect by sustaining a voltage recovery effect of a fuel cell stack over a long period; and to provide a fuel cell power generation system. <P>SOLUTION: This operation method of a fuel cell power generation system is provided with a fuel cell for generating power by supplying a fuel and an oxidizer to a fuel electrode and an oxidizer electrode arranged by interposing an electrolyte between them, respectively, and is characterized by including: a first operation procedure for setting the output voltage of the fuel cell around 0 volt during power generation of the fuel cell when the fuel cell power generation system capable of supplying the output of the power generation to a load is operated; and a second operation procedure for reducing a current supplied to the load immediately after the first operation procedure relative to the load current before the first operation procedure. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
