Synergistically enhancing the corrosion resistance and electrical conductivity of high-nitrogen stainless steel bipolar plates by forming a passive film rich in Cr2O3 and CrN in a simulated environment for PEMFCs

Key Points

• Corrosion resistance and electrical conductivity are enhanced with passive film formation, particularly rich in cr2o3 and crn.
• A significant improvement of up to 20% in both corrosion resistance and electrical conductivity is reported in environments simulating pemfcs.
• Assessment involves the formation of a passive film on high-nitrogen stainless steel bipolar plates in a controlled environment.
• These findings highlight the potential for optimized bipolar plates, improving efficiency and durability in fuel cell applications.
