<P>PROBLEM TO BE SOLVED: To provide a fuel cell system which certainly avoids a fuel cell achieving a high potential state even when a charging quantity of a battery or the like is restricted. <P>SOLUTION: A controller determines whether the battery can accept excessive power ΔP or not (Step S400) when it is determined that an output voltage of the fuel cell needs to be forcibly dropped at Step S300 (Step S300;YES). The controller sets a switching frequency of a DC/DC converter high when it is determined that the battery can not accept the excessive power ΔP (Step S400:NO), and the processing is completed after the excessive power ΔP is accepted by increasing an energy loss of the DC/DC converter (Step S500). <P>COPYRIGHT: (C)2009,JPO&INPIT |
