Stainless Steel Bipolar Plates

A prototype of metallic PEM fuel cell with thin stainless steel bipolar plates is tested for their potential applications in portable electronic products. The bipolar plate is produced by UV-LIGA and electrochemical micro-machining (EMM) technologies. The cathode electrode, the tool, is the mirror image of flow channels. It is produced by the UV-LIGA technology and the dimension is 200μm in width and 500μm in height for the intension to fabricate a serpentine flow channel of 500μm width and 200μm depth. The flow channels on 0.6mm thick SS 316L plates are fabricated by EMM process within 30 seconds with effective area of 625mm2. From the results of cell performance tests, the peak power densities are 0.67 W/cm2 at 0.45 V. During the 5 hours of cell life test, the cell was operated with a constant load of 0.4 V. The peak power density is stable. It just dropped slightly from 0.7 W/cm2 to 0.65 W/cm2. The results demonstrate the UV-LIGA and EMM technologies is an efficient method to fabricate flow channel for stainless steel bipolar plates.

Serpentine Flow Field

The process of stamping stainless steel bipolar plates is developed from initial plate design through manufacturing and use in a fuel cell stack. A stamped design incorporating a serpentine flow field for the cathode and an interdigitated flow field for the anode is designed. This bipolar plate consists of only one piece of thin stainless steel sheet. The process of rubber-pad stamping was chosen to reduce shearing of the thin sheet. Dies were designed and made. Stainless steel plates were stamped, but stress were higher than anticipated and die failure was observed. The plates were tested both in-situ and by doing simulated fuel cell testing. Although sealing was an issue due to lack of proper gaskets and endplates, tests determined that the stamped bipolar plates will work in a PEM fuel cell stack. Dies were redesigned to improve durability. Gaskets and endplates were designed to complete the stack construction.
