Abstract
This review article delves into the recent strides made in the realm of Proton Exchange Membrane Fuel Cell through the exploration of nitride coating materials on Aluminium (Al) alloy-based Bipolar plates (BPs). The study focuses on the advancements achieved in enhancing the performance and durability of these crucial components. Through a comprehensive characterization process, the nitride coatings' impact is assessed, emphasizing critical parameters such as corrosion current density, potentiostat results, and Internal Contact Resistance (ICR). The review highlights the notable advantages brought about by nitride coatings, particularly their corrosion resistance and durability, in mitigating challenges posed by the demanding operational conditions of fuel cells. Additionally, it sheds light on existing challenges, such as coating porosity and adhesion issues, underscoring the importance of ongoing research efforts to optimize these materials. As the exploration of nitride-coated Al alloy BPs progresses, this review anticipates contributing valuable insights to the broader goal of advancing sustainable and efficient energy solutions in PEMFC applications.
