Abstract EN
A new chemical passivation technique, which contained 20 g/L hydrogen peroxide, 3.75 g/L sodium silicate, 1.25 g/L sodium carbonate, 3.75 g/L lactic acid and 0.75 g/L 8-hydroxyquinoline, was used to modify 316 stainless steel with Ag coating (Ag-coated 316SS) as PEMFC bipolar plates.
The results indicated that the compact passive film had been obtained on the surface of Ag-coated 316SS.
The passivation process could not only increase contact angle (from 58∘ to 104∘) but also decreased pinhole defects of Ag-coated 316SS.
Electrochemical test manifested that the passivation process could reduce Ag-coated 316SS's double layer capacitance (Cd), and increase its charge transfer resistance.
So, it provided significant protection against corrosion for Ag-coated 316SS in PEMFC environment.
