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