MULTI-COMPONENT BIPOLAR PLATE FOR AN ELECTROCHEMICAL CELL

摘要

A bipolar plate assembly is provided. The bipolar plate assembly may have a first seal assembly including a first high pressure seal, a second high pressure seal, and an insert plate disposed between the first high pressure seal and the second high pressure seal. The insert plate may have a plurality of ridges formed on an upper surface and a lower surface of the insert plate configured to penetrate into the first high pressure sea! and the second high pressure seal when the first high pressure seal and the second high pressure seal are pressed onto the insert plate, thereby forming the seal assembly. The bipolar plate assembly may also have a frame and a base configured to be joined to form a bipolar plate and define a high pressure zone. The seal assembly when installed in the bipolar plate may be configured to seal the high pressure zone.
