Corrosion behavior of Ti-Pt-coated stainless steel for bipolar plates in polymer electrolyte membranes under water electrolysis conditions.

ABSTRACT: In this study, the corrosion behavior and degradation mechanism of Ti-Pt-coated stainless steel bipolar plates were investigated through electrochemical tests and surface analysis in a polymer electrolyte membrane water electrolysis (PEMWE) operating environment. The coated bipolar plate has a corrosion current density of only 1.68 × 10^-8 A/cm², which is an order of magnitude lower than that of the bare SS316L substrate (1.94 × 10^-7 A/cm²), indicating that its corrosion resistance is superior to that of bare SS316L substrate. However, in the PEMWE operating environment, the protection efficiency of the coating and the corrosion resistance of the coated bipolar plate decreased. The degradation of the coated bipolar plate can be attributed to elect
