Abstract:
1. A fuel cell system comprising: a fuel cell that obtains electric power through electrochemical reaction between hydrogen gas and oxidation gas; an oxidation gas feeding passage for passage of oxidation gas fed to the fuel cell; an impurity adsorbing portion that is disposed on the oxidation gas feeding passage and adsorbs impurities contained in oxidation gas; an impurity outlet passage that connects the oxidation gas feeding passage downstream of the impurity adsorbing means to outside without going through the fuel cell; an impurity emitting portion that causes emission of impurities adsorbed by the impurity adsorbing portion from the impurity adsorbing portion; a flow path regulating portion that leads impurities emitted by the impurity emitting portion to the impurity outlet passage; and a diluting portion that dilutes impurities emitted by the impurity emitting portion.
