This study explores the feasibility of using a relatively rapid technique, die-sinking micro-electrical discharge machining, to fabricate miniature metallic bipolar plates. The flow field is a three-pass serpentine structure, of which both the rib and channel widths are 500 m and the channel depth is 600 m (aspect ratio = 1.2) in a reaction area of 20 mm… (More)
