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.

Impact of graphite on the physicochemical properties of high density polyethylene (HDPE)/copper composites has been investigated at various volume percentages of copper. The two sets of composites are prepared by simple melt blending and injection molding approach. Thermal conductivity increases from 0.5 W m -1 K -1 for pure HDPE to 6.5 and 8 Wm -1 K -1 for 30 and 40 vol.% of copper loading with and without graphite, respectively. A huge increment in synergistic efficiency has been evidenced for the mixed filled polymer composites. Incorporation of graphite has also improved the percolation threshold from 19 to 13 vol.% of copper loading to the HDPE matrix, which indicates the synergistic effect of mixed filler system. Development of leafy morphology of copper promotes large number of inter-particle contacts and hence improves the percolation threshold of the composites. The corrosion resistive, mechanically robust, electrically and thermally conductive composites with good flexural properties and light in weight than conventional metallic bipolar plates suggest it a material of choice for fuel cell devices.
