<P>PROBLEM TO BE SOLVED: To provide a single cell structure for a fuel cell stack including a composite gasket having effective sealing property and capable of reducing tightening pressure of a proton exchange membrane fuel cell (PEMFC) stack to facilitate mounting of the gasket. <P>SOLUTION: When assembling a single cell of the fuel cell stack, this single cell structure for the fuel cell stack including the composite gasket adopts the composite gasket, sealing property is given to one face which becomes a supporting body to ensure rigidity unavailable from pure rubber, and bonding property is given to the other face to bond on a separation plate in order to improve mounting property, thereby improving sealing property by a cross sectional shape of two row beads. Tightening pressure is reduced by use of low hardness rubber material and reduction of bulk to provide an effective sealing structure capable of contributing to the improvement of performance of a fuel cell. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
