<P>PROBLEM TO BE SOLVED: To inhibit a cell seal for fuel cell in which a gasket is integrated with an end part of a metallic separator plate from deforming due to curvature of the separator plate and control formation of a sharpened part such as burr in the end part of the separator plate which may be a starting point of a crack in the gasket. <P>SOLUTION: A turned back edge 2e is prepared in the end part 2a of the separator plate 2 to have a stereoscopic structure in the end part 2a and the gasket 3 is integrated to the end part 2a of the separator plate 2 including the turned back edge 2e without adhesion. Thus the separator plate 2 is strengthened by the stereoscopic structure and the sharpened part such as burr is hidden by the turned back edge 2e. <P>COPYRIGHT: (C)2007,JPO&INPIT |
