- Ni-based amorphous alloys with surface modification by carbon ion implantation are proposed as an alternative
bipolar plate material for polymer electrolyte membrane fuel cells (PEMFCs). Both Ni60Nb20Ti10Zr10 alloys
with and without carbon ion implantation have corrosion resistance as good as graphite as well as much
lower contact resistance than 316L stainless steel in the PEMFC environment. The formation of conductive
surface carbide due to carbon ion implantation results in a decrease in the contact resistance to a level comparable
to that of graphite. This combination of excellent properties indicates that carbon ion implanted
Ni-based amorphous alloys can be potential candidate materials for bipolar plates in PEMFCs.
