Surface modifications of aluminum alloy 5052 for bipolar plates using an electroless deposition process

Novel functionalized carbon nanotubes as cross-links reinforced vinyl ester/nanocomposite bipolar plates for polymer electrolyte membrane fuel cells

“…Metallic materials such as stainless steel, aluminum, titanium and alloy or a protective coating layer on the surfaces of the plates have been widely investigated [9][10][11]. Metallic plates typically have high bulk electrical conductivity, good thermal conductivity, and excellent mechanical properties [7,12].…”

Reviewing Metallic PEMFC Bipolar Plates

“…For cost reduction, the same group treated 5052 alloy chemically and found that that the corrosion resistance and conductivity of chemically treated 5052 alloy could not reach the same levels as the PVD coating [87]. Electrical and electroless depositions of Ni-P, Ni-Mo-P and other Ni-based alloys were also attempted on Al alloys [88][89][90]. It turned out that the corrosion resistance of such surfaces with Ni-based alloys needs further improvement in PEMFC environments.…”

Study of different aluminum alloy substrates coated with Ni–Co–P as metallic bipolar plates for PEM fuel cell applications

“…Aluminum alloys such as AA6061 [18], AA1050 [19], Al 5052 [20] and Al 5083 [21] coated with different deposits were also investigated. These coatings involved electroless deposited NieMoeP [20] and electrodeposited NieCoeB [18], NieFeeCo, NieMoeFe and NieMoeFeeCr [19]. Ternary NieCoeP alloy has been extensively prepared either by electroless [22e27] or electroplating [28e30] deposition techniques.…”
