This study investigates the anti-corrosion potential of graphene coating in electrolytic cells, with the primary objective of improving the longevity and durability of Proton Exchange Membrane Fuel Cells (PEMFCs). Corrosion of bipolar plates poses a big challenge for PEMFCs, resulting in adverse effects on their durability and overall performance. In this study, the effectiveness of graphene as a protective coating for copper-based electrolytic cells is assessed , which serves as a model system to study the change in corrosion behavior with graphene coatings. Initially, a brief fundamental of PEMFCs including the basic operating principles and corrosion-related issues is described. Then, graphene’s material properties and production methods are explored to discuss its potential for mass production and application. Due to graphene’s unique material characteristics, it is suggested that graphene makes it an ideal candidate for coating applications in systems such as PEMFCs. Next, experimentations that involve application of graphene coatings on copper-based electrolytic cells are conducted, and the results are evaluated both visually and quantitatively to observe the coating’s performance in mitigating corrosion and compare the corrosion results of coated samples with those of uncoated control samples to determine the efficacy of the coatings. While the findings of this research provide valuable insights into the potential applications of graphene coatings for corrosion protection, it also highlights the need for further investigation into this area of interest. Future studies are recommended to include a more robust testing framework with more variations of the operating configurations to allow comprehensive understanding of the coating’s effectiveness.
