Figure S4: Influence of the electrolyte concentration on CV curves in O2, relating to a HClO4-concentration-dependent limiting current. Measurements were carried out with GDEs with a loading of 100 µgPt cm-2 and a catalyst-coated area of 0.785 cm2. The size of the Pt wire CE is 2.6 cm2. Reproduced with permission from [5].
