<P>PROBLEM TO BE SOLVED: To provide a fuel cell system having a simple structure disusing an exhaustion process from an anode electrode side, and capable of stably continuing power generating operation. <P>SOLUTION: The fuel cell system detects a density of nitrogen gas in a circulation supply channel 40 at the anode electrode 24 side by a nitrogen density detection part 42, and controls hydrogen gas supplied to the anode electrode 24 by controlling rotation of a pump 38 arranged at the circulation supply channel 40 depending on the nitrogen gas density so as to get into a stoichiometry capable of obtaining a target load current set at a target load current setting part 60. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
