Abstract:A novel metallic glass, Fe50Cr18Mo10C20Si2 (FeMG), is developed
and proposed as
a potential bipolar plate for proton exchange membrane fuel cells.
Its metallic glass nature ensures that there is an oversaturation
of Cr and Mo in the substrate and that a stable Cr–Mo–C-rich
passive film forms with fewer defects. Therefore, FeMG shows higher
impedance, higher stability, higher corrosion resistance, and a lower
ion dissolution rate than SS316 during immersion and electrochemical
tests. A comparison with Ti-based … Show more
