<P>PROBLEM TO BE SOLVED: To enhance the performance of a fuel cell stack by enhancing the exhaust performance of steam from a fuel electrode. <P>SOLUTION: A fuel cell system is equipped with a fuel cell stack 1; an oxidant gas supply passage 6 for supplying air 10 to an air electrode 4; a fuel gas supply passage 5 for supplying hydrogen 9 to a fuel electrode 2; and an inert gas mixing supply means for mixing inert gas with the hydrogen 9. The inert gas mixing supply means is equipped with a condenser 13 removing steam by condensing fuel electrode exhaust gas 11 and exhausting recycle gas comprising inert gas remained after removing steam and hydrogen; and a connection part 18 mixing hydrogen 9 with recycle gas 21 and supplying a mixture to the fuel electrode 2. <P>COPYRIGHT: (C)2008,JPO&INPIT |
