abstract = {This paper investigates the general performance and
durability performance of a high-temperature polymer
electrolyte fuel cell (HT-PEFC) with CrN/Cr-coated SS316L as
bipolar plates and compares this with the bare SS316L and
graphite bipolar plates. Polarization curves are conducted
every 200 h during the 1000 h durability tests for
evaluating the overall performances of the HT-PEFCs with
different types of bipolar plates. An electrochemical model
based on polarization curves, combined with electrochemical
impedance spectroscopy (EIS) and scanning electron
microscopy (SEM), is used for understanding the degradation
mechanisms at play. The CrN/Cr-coated SS316L bipolar plates
show excellent corrosion resistance and performance in a
real HT-PEFC. Thereby, the degradation rate decrease from
ca. $16\%$ of the highest output power with the bare
metallic bipolar plates and graphite bipolar plates to
almost zero with the CrN/Cr-coated steel bipolar plate.},
