具有衬垫的燃料电池隔板和用于制造其的方法

Fuel cell separator with gasket and method for manufacturing the same

Abstract

The present invention provides a fuel cell separator with a gasket manufactured by integrally forming a gasket on one side of a separator; independently injection molding a frame gasket on a frame such that a first airtight portion covers the entire surface of the frame to maintain the shape of the frame gasket and a second airtight portion projects upward and downward from both ends of the first airtight portion; and bringing the first airtight portion of the frame gasket into contact with the other side of the separator with the gasket formed on one side thereof. To create a fuel cell stack in certain embodiments, the invention stacks the second airtight portion of the frame gasket on another second airtight portion of an adjacent unit cell with a membrane-electrode assembly interposed therebetween.
本发明提供了一种具有衬垫的燃料电池隔板和用于制造其的方法。所述方法包括:在燃料电池隔板的第一侧上一体地形成衬垫;在框架上注射成型框架衬垫,使得框架衬垫的第一气密部分基本上覆盖框架的表面以保持框架衬垫的形状,并且使得框架衬垫的第二气密部分从第一气密部分的两端向上和向下凸出,所述注射成型步骤与衬垫的形成步骤相独立地执行;和使框架衬垫的第一气密部分与在第一侧上形成有衬垫的隔板的第二侧接触。
