N2 - We employ a recently developed stripping protocol to examine the equilibrium coverage of oxygenated species and their influence on the oxygen reduction reaction (ORR) and the hydrogen oxidation reaction (HOR). In particular we aim to distinguish between dynamic and steady state conditions and establish if distinctive potential regions exist where the different respective oxygenated species OHad, Oad and Pt-oxide dominate.
