Abstract

Abstract

The effect of pure Ti alloyed with different Ru content on the microstructure and electrochemical behaviour was studied for the need of further improvement in corrosion resistance and conductivity of titanium bipolar plates in proton exchange membrane water electrolysis environments. Results indicated that the α-Ti equiaxed grains were refined, the corrosion resistance was improved with the increase of Ru content. The Warburg impedance appeared in the low frequency region of impedance spectroscopy obtained at OCP. When the Ru content is below 0.08%, the passivation film formed by polarizing at 0.8 V vs Ref for 6 h exhibits p-type semiconductor behavior, and the conductivity remains constant.
