Abstract

Potentiodynamic Pt/C fuel cell catalyst corrosion has been studied as a function of chloride concentration with an electrochemical flow cell (EFC) coupled with highly sensitive ICP-MS. The Pt corrosion mechanism changes significantly: the anodic corrosion is much enhanced compared to the cathodic corrosion that prevails in electrolytes without Cl−.
