<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of suppressing decrease of detection accuracy of a sensor arranged on an oxidant gas flow passage due to effects of impurities, and degradation of the sensor. <P>SOLUTION: The fuel cell system comprises the oxidant gas flow passage going through an air electrode of a fuel cell, a plurality of sensors provided on the oxidant gas flow passage, and a chemical filter arranged on an upstream side of the plurality of the sensors on the oxidant gas flow passage for adsorbing the impurities contained in the oxidant gas to itself. Because the impurities are eliminated by the chemical filter, action of the impurities on the respective plurality of the sensors arranged on a downstream side can be suppressed, and accuracy of the sensors can be maintained. <P>COPYRIGHT: (C)2008,JPO&INPIT |
