A comprehensive comparison of state-of-the-art manufacturing methods for fuel cell bipolar plates including anticipated future industry trends

Design and Modeling of Metallic Bipolar Plates for a Fuel Cell Range Extender

“…To accomplish this constraint, the width of channel and land were kept identical, and the channel depth of the model was adjusted accordingly. Furthermore, the exact angle of the channel walls will be a result of the final production process [22,40,69]. For the design, a value of α = 15 • is used.…”

“…The overall production process combines the techniques of calendering, laser welding, laser cutting, coating, and stack assembly. Each production step adds some requirements to the final flow field plates, as summarized by Porstmann et al [22]. In general, there are two different design options for bipolar plates, which depend on the plate material.…”

“…In general, there are two different design options for bipolar plates, which depend on the plate material. There are compact plates (mostly graphitic) where structures may be milled or thin metallic plates which can be stamped [22,23]. For graphitic plates, it is possible to design the flow fields for anode, cathode and coolant more or less independently.…”

Creep fracture parameter C* solutions for semi‐elliptical surface cracks in plates under tensile and bending loads

“…The plate structures are also often used in high temperature conditions, such as the nuclear fuel assembly and fuel cell electrode plate. [1][2][3][4] For defective plates under high temperature conditions, the initiation and propagation of creep or creep-fatigue cracks are the main failure modes. [16][17][18] It is not appropriate to apply K or J integral to describe the stress-strain field at crack tip region.…”

“…The plate structures can be often found in many industrial equipments and devices. [1][2][3][4] Thus, a great deal of researches have been carried out to evaluate structural integrity of flawed plates. [5][6][7][8][9][10][11][12][13][14] Raju and Newman [5][6][7] analyzed distribution of stress intensity factor K along the crack front for a cracked plate structure under bending and tensile loads, and then, the K solutions were given based on finite element calculation.…”
