Abstract

An electrochemical study of Ni20Cr, NiCrAlY and Cr3C 2(NiCr) alloys used in coating form made with the Tafel extrapolation and Resistance techniques for polarization. The icorr values obtained for Ni20Cr and NiCrAlY coatings, the material dissolution, and the low resistance to corrosion eliminates the possibility that these coating could be candidates for construction bipolar plates for PEM type fuel cells; however with the Cr3C2(NiCr) coating, icorr values below 0.016 mA/cm2 were obtained. Materials must fulfill this criterion to be considered as candidates in applications such as a bipolar plate.
