<P>PROBLEM TO BE SOLVED: To control power generation appropriately when water remains in a fuel cell. <P>SOLUTION: A fuel cell system includes the fuel cell, a secondary battery, a control part for controlling power supply from the fuel cell and secondary battery to an external load, and a requested output acquisition part for acquiring a requested output. The control part is configured by including: acquiring a water distribution in the fuel cell; determining a current limit value of the fuel cell according to the water distribution; supplying power depending on the requested output from the fuel cell system to the external load according to at least the current limit value; and if a predetermined threshold of water or more remains in the fuel cell and predetermined first electrical energy or more is stored in the secondary battery, reducing an output from the fuel cell by reducing the limit value of current from the fuel cell below the current limit value determined according to the water distribution and also increasing an output from the secondary battery. <P>COPYRIGHT: (C)2011,JPO&INPIT |
