“…64 Metallic BPP fabrication process can generally be divided into four ordered steps: flow channel design, forming the flow channels on the plate, joining the plates, and finally coating the surface. 64 During fabrication, the most frequent defects associated with such processes are warping, distortion, and cracking. The fabrication process must not negatively affect the contact resistance between the BPP material and GDL.…”

Summary Electrolysis coupled with renewable energy resources is the most promising method for green hydrogen production. Polymer electrolyte membrane water electrolyzer (PEMWE) has attracted attention due to its ability to produce high‐purity, compressed hydrogen at relatively mild operating temperatures (70°C‐90°C). The highest cost contributor of the PEMWE stack are the bipolar plates (BPPs). Owing to the severe operating conditions (acidity from the membrane and high localized oxygen concentration) of the PEMWE stack, appropriate material and fabrication are crucial to ensure high performance and durability. The role of BPPs in mass transport and electrical charge transfer must be further understood and correlated to its specific application in PEMWE. At the most basic level, BPPs must have low interfacial contact resistance and high corrosion resistance to withstand the conditions within the stack. The most common base materials for BPP construction include austenitic stainless steel (SS316 and SS403) and Ti due to their flexural strength and ease of mass production. A coating layer is also necessary to protect the substrate from corrosion, and the most popular materials include TiN and other noble metals with nonpassivated oxides and reliable electrical conductivity. The compromise between material robustness and cost is currently a delicate balance toachieve.

“…Currently, only stamping and hydroforming are considered as good manufacturing routes for high‐volume production . What hydroforming lacks in process time, it compensates with a better surface finish that contributes to better corrosion resistance and less expensive tooling costs, as well as less forming defects.…”

Proton exchange membrane fuel cells (PEMFCs) generate electricity utilizing the energy of electrochemical reactions of fuel (H2) and oxidants (O2/air). As they emit no toxic gases during the process, they are considered as a clean energy source that can be beneficial and might replace the use of fossil fuels. To compose a FC stack, an essential component, bipolar plates (BPs), is needed. They have several roles to fulfill during PEMFC stack operation, and there are many challenges when it comes to BPs metal‐based materials and their sustainability, durability, and longevity. Finding suitable metal and alloy materials is a significant task as BP materials should have multiple qualities that sometimes come at the expense of one another. As BPs constitute a significant part of PEMFC stack by means of volume, weight, and costs, the pursuit of the most suitable and least expensive metal‐based materials is comprehensible. In this Review, different metal and alloy types (copper, nickel, titanium, and aluminum alloys) and their own particular challenges are discussed, emphasizing the most important family of materials candidates—stainless steels.

“…45 In terms of a bipolar plate application, suitable thickness is relevant to the depth of reactant ow channels located on a BP surface and copper layer peeling off. The depth of ow channels for a fuel cell application was typically imposed in the range of 0.50-0.53 mm, 46 but some research work designed the channel depth approximately 0.760 mm and 1.00 mm. 47,48 The channel depth inuences on fuel cell performance.…”
