“…Jin et al [34] used dynamic loading during stamping to fabricate stainless steel bipolar plates for fuel cells and performance evaluation of individual cells, which was found during experiments to study the stamping process of stainless steel bipolar plates under different loading conditions. They found that dynamic loading during bipolar plate forming can improve the formability of metal plates [35]. The bipolar plate stamping machine is shown in Fig.…”

Bipolar plates are one of the most important components in fuel cell stacks and have multiple functions. Compared with composite materials, bipolar plates of metallic materials have superior electrical and thermal conductivity, good mechanical strength, high chemical stability, very wide choice of alloys, and coating techniques are employed to improve their corrosion resistance and reduce their bottom contact resistance. This paper investigates the selection of materials and stamping and forming of metal bipolar plates in the hope that this research can promote the development of metal bipolar plates for fuel cells. On this basis, we expect to innovate the material and fabrication process of metal bipolar plates, reduce their cost, and promote their commercialization.

“…Fuel cells are electrochemical devices that convert the chemical energy of reactants (a fuel and an oxidant) into electricity and water as the only byproduct. Amongst different types of fuel cells, Proton Exchange Membrane (PEM) fuel cells are considered an appropriate candidate for the automotive industry because of their high energy density, high efficiency, zero emission, fast startup (due to the solid immobile electrolyte), continuous operating and low operation temperature (50 to 100 • C) [2][3][4][5][6][7][8].…”

“…The bipolar plates constitute about 80% of the weight and more than 40% of the total stack cost of PEM fuel cells. [3][4][5]9,10 Hence, finding a costeffective material for the bipolar plates can pave the path for the commercialization of PEM fuel cells and enable them to compete with other energy sources (like fossil fuels) in the automotive industry. 2 Bipolar plates are multi-functional components that conduct the current from cell to cell, facilitate thermal and water management and distribute reactant gases in fuel cells.…”

Aluminum is an appropriate candidate for bipolar plates in proton exchange membrane (PEM) fuel cells because it reduces the final cost and weight of the fuel cell stack in comparison to stainless steel, titanium and graphite. However, a conductive coating layer is essential to protect it against corrosion. In this study, the electrochemical behavior of aluminum coated with titanium and amorphous carbon layers by physical vapor deposition is evaluated. The main goal is to investigate the corrosion protection performance and the possible failure reasons of the coating in sulfuric acid solutions (with different pH values) in the presence of 3 ppm sodium fluoride and elevated temperature (80 • C) to mimic the working conditions of PEM fuel cells. To reach our aim, electrochemical tests are combined with surface analysis techniques. It is revealed that at low pH values (pH= 2 and 3), the coating fails due to the acidity of the electrolyte solutions. However, in the electrolyte with pH= 4, present fluoride ions interfere and consequently lead to localized failures. It is noticed that the presence of defects in the coating is a key parameter in the application of coated aluminum as bipolar plates in PEM fuel cells.

“…As metallic BPPs alone do not satisfy DOE targets, research has focused on coating development to improve both the corrosion properties and interfacial contact resistance. Many different techniques exist for applying coatings, including: (i) physical vapour deposition (PVD), (ii) chemical vapour deposition (CVD), (iii) electroplating and electrophoretic deposition . When comparing the coating methods in terms of scalability and cost, it can be noted that physical and chemical vapour deposition methods require batch production which could limit mass production and increase cost .…”

Two materials, polyaniline (PANI) and titanium nitride (TiN), used for bipolar plate (BPP) coatings have each shown promise in improving the corrosion resistance and contact resistance, respectively, of metallic bipolar plates. Polyaniline was shown to provide a barrier for the bipolar plate and to effectively lower the corrosion currents observed in ex situ corrosion tests. However, the interfacial contact resistance (ICR) between polyaniline coatings and gas diffusion layer (GDL) is high and results in high electrical losses. On the other hand, TiN is reported to achieve good conductivity and in some cases improved corrosion resistance. The two materials have also been investigated together in a composite coating and showed promising results, but the contact resistance of the coating was still too high for use in a commercial fuel cell. In this study, the application of an additional layer of TiN over the TiN‐polyaniline composite coating (a bilayer coating) is investigated. Composite bilayered PANI TiN coatings were deposited upon SS316L substrates. The optimized coating achieved U.S. Department of Energy (DoE) targets with potentiostatic corrosion currents of ∼0.024 μA cm−2 and ICR values of 11.2 mΩ cm2. PANI polymerization was confirmed, using Fourier‐transform infrared (FTIR) spectroscopy and TiN loadings were investigated with energy dispersive X‐ray (EDX) spectroscopy .
