“…The corrosion rate obtained in this study for bare and coated AISI 1020 is somewhat higher compared to previous reports [7][8][9][10][11][12]. For instance, Bai et al [7,12] showed that the corrosion current of bare steel sample is 6.34 × 10 −4 A/cm 2 while Ni-electroplated pack chromized carbon steel sample shows in the order of 10 −8 A/cm 2 .…”

“…Metals such as titanium [3], copper [4], aluminum [5], stainless steel [6], carbon steel [7][8][9][10][11][12], and various other alloys [13,14] have been evaluated for PEM fuel cell BPPs. Most of these studies conclude that although the cost of manufacturing is low for metallic bipolar plates, the corrosion resistance is also low and hence are not suitable for BPPs.…”

In here, we report on the pulse electrodeposition of nickel-chromium-phosphorous (Ni-Cr-P) coatings on AISI 1020 low carbon steel using an aqueous electrolyte consisting of NiCl 2 , CrCl 3 , and NaH 2 PO 2. We evaluated the effectiveness of Ni-Cr-P coatings for polymer electrolyte membrane fuel cell metallic bipolar plates. Coatings deposited at pH 3.0 and room temperature show nearly three orders improvement in corrosion resistance compared to bare AISI 1020. The corrosion current (I corr) of Ni-Cr-P samples coated at 25 °C is 1.16 × 10 −4 A/cm 2 , while that of bare carbon steel is 1.05 × 10 −2 A/cm 2. The improvement in corrosion resistance is due to the increase in Cr content in the Ni-Cr-P coatings. Cr forms a stable oxide barrier layer and inhibits pitting corrosion. The interfacial contact resistance increases with an increase in Cr content and immersion time in the corrosion media. The increase in interfacial contact resistance is also due to the formation of a stable oxide barrier.

The electrical conductivity, corrosion resistance and hydrophobic property of bipolar plate are important factors to affect the overall performance of proton exchange membrane fuel cell (PEMFC). In order to improve the performance of bipolar plate, ZrC coating has been prepared on bare Ti plate by plasma surface modification technology. From the microscopic morphology characterization, it can be found that the surface of ZrC modified plate is smooth without obvious defect. The potentiodynamic polarization and potentiostatic polarization tests are measured in cathodic and anodic environment of PEMFC. The result shows that the corrosion current density of ZrC coated Ti plate decreases by 1-2 orders of magnitude compared with bare Ti plate. Moreover, the interfacial contact resistance (ICR) decreases from 110 mΩ cm 2 to 7.70 mΩ cm 2 under the compaction force of 140 N cm-2. In addition, the ICR of ZrC coated Ti plate slightly increases after potentiostatic polarization, indicating that a good electrical conductivity and durability is obtained by ZrC coated Ti plate. Furthermore, the ZrC coated Ti plate has a lower water contact angle (105°) than bare Ti plate (76°), indicating a better hydrophobic performance for water management.
