<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of reducing a start time of the system, and of preventing malfunction of a pressure sensor. <P>SOLUTION: This fuel cell system 1 includes: a fuel cell 10; a hydrogen tank 22 supplying hydrogen gas to the anode side of the fuel cell 10 through a hydrogen supply passage 43; an air pump 21 supplying air to the cathode side of the fuel cell 10 through an air supply passage 41; a bypass 46 communicating with the hydrogen supply passage 43 and the air supply passage 41; an air introduction valve 46 arranged on the bypass 46, and capable of controlling the volume of gas flowing through the bypass 46; and a pressure sensor 51 having a diaphragm deformable by the pressure of the hydrogen gas, and detecting the pressure of the hydrogen gas by detecting the amount of displacement of the diaphragm. The pressure sensor 51 is arranged at a part within the bypass 46 between the air introduction valve 461 and the hydrogen supply passage 43. <P>COPYRIGHT: (C)2009,JPO&INPIT |
