Key Points

The aim is to evaluate the corrosion resistance of austenitic stainless steels in an anode environment simulated for AEM water electrolysis.
Conducted potentiostatic polarization in an environment mimicking AEMWE anodes.
Analyzed the formation of corrosion products on stainless steel surfaces.
Assessed the increase in interfacial contact resistance (ICR).
ICR significantly increased after polarization due to the formation of heterogeneous coatings.
Surface coatings included nickel oxyhydroxide/oxide and chromium-iron oxides.
Low dissolution rates of chromium and iron suggest potential for modified stainless steel surfaces in AEMWE applications.

Evaluates corrosion resistance in austenitic stainless steels, suggesting modifications for AEMWE applications.
