Abstract
This study investigates the effect of 1 mmol dm-3 concentrations of a selection of small cationic molecules on the performance of a fuel cell grade oxygen reduction reaction (ORR) catalyst (Johnson Matthey HiSPEC 3000, 20 mass% Pt/C) in aqueous KOH (1 mol dm-3). The cationic molecules studied include quaternary ammoni
