<P>PROBLEM TO BE SOLVED: To avoid unnecessary transition to a fail-safe action of a fuel cell system, through determination of offsetting abnormalities of a pressure sensor and elimination of false determination of failures of a regulator due to the abnormalities of the sensor. <P>SOLUTION: The system is provided with a regulator for adjusting pressure of reaction gas from a reaction gas tank, a fuel cell generating power with supply of reaction gas with pressure adjusted by the regulator, a first pressure sensor 31 for detecting a primary-side pressure of the regulator, and a second pressure sensor 32 for detecting pressure of a secondary-side pressure of the regulator. It is also provided with an abnormality determination means for determining that the second pressure sensor 32 suffers from offsetting abnormalities if a pressure value detected by the second pressure sensor 32 is higher than that detected by the first pressure sensor 31, in comparison of the value detected by the first sensor 31 with that detected by the second sensor 32. <P>COPYRIGHT: (C)2010,JPO&INPIT |
