PEM water electrolyzers are operated with deionized or highly purified water. However, metallic impurities can appear in the pipes as well as in the inner compartment due to corrosion of the metal parts of the electrolyzer cell as the bipolar plate (BPP) or the porous transport layer (PTL). The dissolved ions from the cell components have an influence on the degradation and may impact the catalyst activity. Our objective is to shed light on these processes in the case of two selected metal ion contaminations, which helps us understand the relevance of selecting proper catalyst materials for acidic water splitting. In this study, the impact of cationic impurities on the electrocatalytic activity and stability of IrO
