Fuel cells represent a revolutionary and sustainable approach to energy conversion, offering a clean alternative to traditional combustion-based power generation. These electrochemical devices convert the chemical energy of a fuel, typically hydrogen, directly into electricity. The fundamental working principle involves the electrochemical reaction between hydrogen and oxygen, facilitated by a catalyst, to produce electricity, water, and heat as byproducts in Proton Exchange Membrane (PEMFC). This strategic use of aluminum (Al) alloy for Bipolar plates (Bp) aligns with the industry's commitment to advancing materials and design methodologies, ultimately promoting the optimization of fuel cell technology in terms of performance, durability, and economic feasibility. This comprehensive review investigates recent progress in the development of multilayer coatings tailored for Al alloy-Bp in PEMFCs. Al alloys are a preferred substrate material due to their cost-effectiveness, lightweight nature, and high thermal conductivity. However, challenges such as corrosion, electrical conductivity, and interfacial contact resistance have spurred extensive research into innovative coating solutions. The review critically examines various coating materials, deposition techniques, and performance evaluation methods aimed at addressing the challenges associated with al alloy Bp. Special emphasis is placed on corrosion-resistant coatings, conductive layers, and interfacial modifiers. The assessment encompasses both established technologies and cutting-edge approaches, including nanocomposite coatings, self-healing materials, and advanced characterization methods. By synthesizing and analyzing existing literature, this review provides a comprehensive overview for researchers, engineers, and policymakers involved in advancing PEMFC technology. The findings underscore the crucial role of multilayer coatings in augmenting the performance and longevity of al alloy-based Bp, offering valuable insights to guide further research and development in the pursuit of efficient and durable fuel cell systems. In comparing the aluminum grades Al-356, Al-5052, Al-6061, and Al-7075, it is observed that Al 5052 exhibits lower corrosion density, providing greater efficiency compared to other aluminum grades. In the case of Al 356, the potentiostatic result yields a lower value than that of other aluminum grades. Consequently, these findings suggest a tendency for favorable corrosion resistance and electrodeposition in both Al 5052 and Al 356, making them noteworthy choices in applications requiring these particular material characteristics.

Ni–W/Al2O3 nano-composites were electrodeposited on mild steel substrate for mechanical and corrosion resistance applications. This study focused on the preparation of Ni–W/Al2O3 nano-composite coating with various quantity of Al2O3 incorporations. The addition of Al2O3 in the electrolytes were varied from 1–10 g/L in electrolytes and the Al2O3 incorporation in Ni–W/Al2O3 nano-composite coatings were obtained from 1.82 to 13.86 wt.%. The incorporation of Al2O3 in Ni–W alloy matrix influenced the grain size, surface morphology and structural properties were observed. The distributions of Al2O3 particle in alloy matrix were confirmed using electron microscopy (FESEM and TEM) and EDAX mapping analysis. The crystal structure informations were studied using X-ray diffraction method and it confirms that the deposits having cubic crystal structure. The better corrosion rate (0.87 mpy) and microhardness (965 HV) properties were obtained for the Ni–W/Al2O3 nano-composite coating with 13.86 wt.% of Al2O3 incorporations.

“…[1,5] On the other hand, metallic BPs are reported as less permeable, more robust, thinner, and lighter, but are prone to severe corrosion issues and imply higher production costs. [1] In the past decade, conductive and corrosion-resistant coatings have been proposed to prevent the corrosion of metal BPs, [1][2][3][4][8][9][10][11][12] that is, combining the assets of both materials to enable the use of lower grade metals.

The straightforward synthesis and application of conductive and corrosion‐protective composite coatings suitable for the preparation of bipolar plates of proton exchange membrane fuel cells (PEMFCs) are achieved by a scalable and solvent‐free atmospheric plasma deposition process. Small three‐dimensional (3D) carbon black nanoparticles and large two‐dimensional (2D) natural graphite flakes are investigated independently and together as conductive fillers. It is demonstrated that the dual‐sized conductive fillers strategy traditionally used for the preparation of composite bipolar plates is not transposable for the proposed atmospheric plasma deposition process. Only the composite coatings prepared from large 2D natural graphite flakes enable a significant decrease of the corrosion current in simulated proton exchange membrane fuel cell conditions while ensuring interfacial contact resistance in the order of several tens of mΩ·cm2.
