<P>PROBLEM TO BE SOLVED: To provide a fuel cell system in which both improvement in drainage of an anode electrode and reduction suppression of power generation efficiency are made compatible. <P>SOLUTION: The fuel cell system is equipped with a fuel cell 10 to carry out power generation by electrochemical reaction as an anode gas and a cathode gas are supplied, an anode gas supplying means 3 to supply the anode gas to an anode electrode of the fuel cell 10, a cathode gas supplying means 2 to supply the cathode gas to a cathode electrode of the fuel cell 10, and a cathode off-gas supplying means 5 to supply a cathode off-gas from the cathode electrode to the anode electrode a power generation of the fuel cell 10. The cathode off-gas supplying means 5 controls a cathode gas supply amount to the cathode electrode so that it may have a cathode utilization rate corresponding to water discharge characteristics of the anode electrode. <P>COPYRIGHT: (C)2008,JPO&INPIT |
