The broad use of (stainless steel) SS 316 L bipolar plates (BPs) in proton exchange membrane fuel cells relies (PEMFC) on high conductivity and corrosion resistance. To enhance the properties stainless steel, this study applies ion implantation heat treatment to form a non-homogeneous modified layer L. injection C Mo ions surface caused irradiation damage, producing holes. But with ion-implanted samples, irradiation-damaged will be repaired certain extent. current density (Icorr) 600 °C sample kinetic potential test (5.32 × 10-4 A/cm2) was 54% lower than that naked (1.17 10-3 A/cm2). In electrostatic test, stabilized at low value (about 0.26 μA/cm2), lowest concentration dissolved metal (Fe2+ 2.908 mg/L). After anodic polarization, interfacial contact resistance (ICR) (Mo+C)600-1 much untreated Heat experiments show samples treated for 1 h exhibit significantly higher This improvement is mainly due under these conditions, which facilitated formation carbides from implanted elements. Ion steel passive film These findings are useful altering BPs.
