<P>PROBLEM TO BE SOLVED: To suppress deterioration of a catalyst during operation of a fuel cell. <P>SOLUTION: This control method of a fuel cell using a catalyst metal as an electrode catalyst includes: a step S1 for detecting load fluctuation of the fuel cell; a step S2 for detecting a cell voltage between an anode and a cathode of the fuel cell when the load fluctuation is detected; and steps S4-S6 for regulating, to a predetermined value, humidity of at least either of a fuel gas supplied to the anode and an oxidizer gas supplied to the cathode when the detected cell voltage is in a predetermined voltage range. <P>COPYRIGHT: (C)2007,JPO&INPIT |
