<P>PROBLEM TO BE SOLVED: To improve the reliability of a solid polymer electrolyte fuel cell by preventing the deterioration of a solid polymer electrolyte membrane upon the interruption of an operation, in the solid polymer electrolyte fuel cell using an oxygen separation membrane. <P>SOLUTION: The deterioration of the solid polymer electrolyte membrane 1 is prevented by communicating with an inlet manifold 5 of fuel gas through the oxygen separation membrane 21 separating oxygen gas molecules from nitrogen gas molecules, making flow nitrogen gas on hydrogen side, and quickly exhausting hydrogen gas upon the interruption of the operation. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
