Abstract
Official abstract text for this publication.
The present invention provides an apparatus and method for manufacturing a metal separator for a fuel cell, which can manufacture large-sized metal separators in large quantities using metal plates such as stainless steel by thermoplastic deformation using an incremental and synchronized rubber molding process.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for manufacturing a large-sized metal separator for a fuel cell using an incremental rubber molding process, the method comprising: placing a metal plate on an upper surface of a plurality of lower dies disposed horizontally adjacent to each other; pitch-transferring the lower dies on which the metal plates are placed, respectively, in directions horizontally opposite each other along rails mounted on a working plate to a pressing means by a trans…
