Document Type and Number:
Japanese Patent JP2010212001
Kind Code:
A
Abstract:

To mold a gasket with a uniform clamping margin by granting fuel battery constituent components with the same load as at clamping without being affected by variations of thicknesses of the constituent components and a separator making up a cell in a simple structure without at all giving rise to unnecessary parts.

A separator 3 with a manifold hole 3h not yet formed and the fuel battery constituent components 2 are laminated and inserted into a molding die 1 for clamping, and, while a load to be granted at clamping is granted to the fuel battery constituent components 2 by a load-granting part 15, a material of the gasket 6 is filled in injection into a cavity 13, and then, the gasket 6 is integrally molded with peripheries of the fuel battery constituent components 2 and one of the faces of the separator 3, after which, the gasket 6 and the separator 3 molded are punched out to form an inner periphery face 6a of the gasket 6 constituting a manifold 5 and a manifold hole 3h of the separator 3.
