<P>PROBLEM TO BE SOLVED: To provide an operational method for a fuel cell power generation system which maintains a voltage recovery effect of a fuel cell stack over a long period of time and exhibits an excellent voltage drop suppression effect. <P>SOLUTION: A fuel cell power generation system comprises a fuel battery 1 generating power by supplying a fuel and an oxidant respectively to a fuel electrode 1a and an oxidant electrode 1b which are disposed across an electrolyte, and can supply the power generation output to a load 7. An operational method for the fuel cell power generation system includes a first operation procedure for setting an output voltage of the fuel battery 1 to less than 0.01 V in a state in which the fuel is supplied to the fuel electrode 1a when the fuel battery 1 is stopping power generation, and a second operation procedure for increasing an output voltage of the fuel battery 1 to a voltage higher than at normal power generation immediately after the first operational procedure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
