<P>PROBLEM TO BE SOLVED: To provide a fuel cell system and a system, which suppresses moisture adherence to a pressure sensing section. <P>SOLUTION: A fuel cell system 1 comprises: a supply flow path 22 for supplying a reactant gas to a fuel cell 2; a pressure sensor P1 having a pressure sensing section 102 exposed to a reactant gas for detecting pressure of the reactant gas; and a circulatory flow path 23 for circulating a reactant offgas emitted from the fuel cell 2 in a supply flow path 22. On an upstream side of the pressure sensor P1, there is provided an injector 25 for injecting a reactant gas, with the pressure sensor P1 being connected to a negative-pressure generating area 84 in which a negative pressure is generated upon injection of the reactant gas by the injector 25. <P>COPYRIGHT: (C)2008,JPO&INPIT |
