Abstract
The present disclosure provides an end plate for a fuel cell including a sandwich insert, in which a metal insert has a sandwich insert structure including a plurality of stacked plates, thereby securing strength and achieving a lightweight structure. The sandwich insert is manufactured by staking two or more plates, each having a specific shape, followed by injection molding the sandwich insert with a plastic injection molded body, thereby securing strength and also achieving a lightweight structure, contrary to a conventional integral metal insert.
