<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of removing condensed water condensed in a gas passage by a simple constitution and performing a stable operation. <P>SOLUTION: A cell voltage V is detected after starting an operation of a fuel cell (S20). It is determined whether or not the cell voltage V is lower than a prescribed reference voltage V1 (S30). When the cell voltage V is the reference voltage V1 or higher (No at S30), the cell voltage V is detected again (S20). Further, when the cell voltage V is lower than the reference voltage V1 (Yes at S30), connection between the fuel cell and its load is released, and the operation of the fuel cell is stopped (S40). A first blocked water dissolution operation is performed after stopping the operation of the fuel cell (S50). After gas pressure in an anode is raised higher than prescribed pressure by intercepting the discharge of gas from the anode at the first blocked water dissolution operation, the condensed water is discharged in the gas passage of the anode by discharging the pressurized gas from the anode. <P>COPYRIGHT: (C)2009,JPO&INPIT |
