<P>PROBLEM TO BE SOLVED: To provide a fuel battery system capable of suppressing unexpected variations in the target power, at high-potential avoidance control operation. <P>SOLUTION: The fuel battery system sets a high-potential avoidance target voltage value (step 501); converts the high-potential avoidance target voltage value into a target power value, based on a voltage-to-power characteristic map of a fuel cell (step 502); limits the target power value in a range of the prescribed upper limit value and lower limit value (step 503); limits the output voltage of the fuel cell to the high potential avoidance target voltage; or lower and controls operation of the fuel cell, based on the target power value (step 504). Thereby, unexpected variations in the target power value by erroneous estimation of output characteristics caused by instantaneous drop of the high potential avoidance target voltage can be suppressed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
