Abstract

A separator for a fuel cell includes a metal plate which defines a passage and a manifold, frames having gaskets which are integrated therewith using injection, and a bonding unit for bonding the frames to the metal plate. The gaskets may be differently formed. This resolves process interference problems between conductive surface treatment and gasket cross-linking, obviates deburring of the gasket, and preventes poor injection of the gaskets, which ensures stable quality of the separator, increases productivity and decreases the manufacturing cost.

First claim

What is claimed is:

1. A separator for a fuel cell, comprising:
a metal plate which defines a passage and a manifold;
frames having gaskets which are integrated therewith using injection; and
a bonding unit for bonding the frames to the metal plate,
wherein the bonding unit comprises:
a bonding hole disposed in the metal plate; and
bonding protrusions including one bonding protrusion, which protrudes from the frame positioned at one side of the metal plate and passes thr…
