<p><P>PROBLEM TO BE SOLVED: To improve the output of a fuel cell stack by uniformizing the amount of oxidant supplied to the parts of the fuel cell stack, by employing such oxidant supply flow path for supplying the oxidant to an oxidant inlet of the fuel stack as comprising a plurality of sub flow paths divided along the flow direction of the oxidant; and to properly control the output of the fuel cell stack, by controlling the amount of the oxidant supplied to the parts of the fuel cell stack according to the operation state, resulting in smaller size of the entire system. <P>SOLUTION: The fuel cell system comprises a fuel cell stack in which a fuel cell sandwiching an electrolyte layer between a fuel electrode and an oxygen electrode is stacked with a separator in-between, in which a fuel electrode is formed along that fuel electrode and an oxidant flow path is formed along the oxidant electrode, with an oxidant inlet of the oxidant flow path formed at each separator. It also comprises the oxidant supply flow path that supplies the oxidant to the oxidant inlet. The oxidant supply flow path consists of a plurality of sub flow paths divided along the flow direction of the oxidant. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
