<P>PROBLEM TO BE SOLVED: To prevent an excessive load on an electrolyte membrane when power generation is stopped while preventing the shape of a catalyst carrier in a cathode from changing. <P>SOLUTION: A fuel cell system with a fuel cell, comprises a stopping unit (S110) in which the supply of fuel gas and oxidant gas to the fuel cell is stopped at a prescribed timing, a voltage variation rate calculating unit (S120) which calculates the variation rate of power generation voltage of the fuel cell after the stop in the stopping unit, and a fuel re-supplying unit (S130-S140) which re-supplies the fuel cell with the fuel gas when the variation rate of power generation voltage calculated in the voltage variation rate calculating unit has a positive value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
