Abstract
The corrosion behaviour of (Ni60Nb40) and Ni-Nb-M (M = Zr, Mo, Ta & Pd) meltspun ribbons was studied by electrochemical and chemical methods at PEMFC environments. The doping of Mo, Pd and Ta decreased the corrosion and passivation current densities, whereas the addition of Zr induced the opposite effect. To understand the change of corrosion behaviour induced by these additional elements, the surface composition and surface oxide layer thickness were analyzed by XPS method.
