<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of maintaining a stable operating state of a fuel cell even in load fluctuation. <P>SOLUTION: A fuel cell system 1 comprises: a fuel cell 2; a fuel gas system 4 in order to supply fuel gas to the fuel cell 2 and circulate gas exhausted from the fuel cell 2; a purge valve 29 in order to exhaust the gas from the fuel gas system 4; and control means 6 to control an open-close operation of the purge valve 29. The control means 6, in the whole load region, controls the open-close operation of the purge valve 29 so that partial pressure of impurities in the fuel gas system 4 becomes constant. <P>COPYRIGHT: (C)2012,JPO&INPIT |
