      abstract     = {In this work, a bilayer CrN/Cr coating was deposited on the
                      surface of a 0.1 mm-thick SS316L specimen with a size of
                      60 × 60 mm2 by means of a reactive magnetron
                      sputtering method. Using a specially-designed
                      electrochemical cell for simulating the HT-PEFC environment,
                      various electrochemical tests, including potentiodynamic
                      polarization, potentiostatic polarization and EIS, were
                      performed in order to evaluate the anti-corrosion properties
                      and stability of the bilayer CrN/Cr coating in simulated
                      HT-PEFC environments. Additionally, ex-situ
                      characterizations using XRD, SEM + EDX and ICR were carried
                      out to investigate the crystal structure and composition of
                      CrN/Cr coating, surface morphologies and the interfacial
                      contact resistance of samples before and after corrosion
                      tests. The results show that the bilayer CrN/Cr coating
                      could provide a more than $99.9\%$ protective effect on the
                      substrate (SS316L) in the simulated HT-PEFC environment at
                      RT and 130 °C, and reduce the corrosion rates of BPPs more
                      than 600 times in both the simulated cathodic and anodic
                      environments of a HT-PEFC. Furthermore, an ICR value of
                      CrN/Cr SS316L (5.5 mΩ cm2) is around one order of magnitude
                      lower than that of the bare SS316L substrate
                      (47 mΩ cm2) in a typical pressing force for assembling
                      fuel cells (140 N cm−2).},
