Erratum: Deconvolution of ECSA Loss and Transition Metal Leaching upon Voltage Cycling Induced Aging of Pt-alloy Cathode Catalysts in a PEM Fuel Cell (Journal of The Electrochemical Society (2025) 172 (084502) DOI: 10.1149/1945-7111/adf09e)

At several occurrences in the published paper, the voltage cycling conditions were stated erroneously as "H₂/air at 80 °C/100% RH"instead of the correct "H₂/N₂ at 80 °C/95% RH."Any voltage cycling reported in the original paper was conducted under H₂/N₂ at 80 °C/95% RH. The error appears at the following points in the original paper: • Results and Discussion: caption of fig 7 • Appendix: caption of fig A2 • Appendix: subsection A2 Also, in the appendix, subsection A3 and in the corresponding Fig. A3, the relative humidity was stated incorrectly as "H₂/N₂ at 80 °C/100% RH"instead of the correct "H₂/N₂ at 80 °C/95% RH."Another error occurred in the Results and Discussion section, in the subsection "Effect of voltage cycling parameters on ECSA loss,"in the paragraph below Fig. 4. The sentence in the original paper "This is ascribed to the higher Pt surface energies of the larger particles, which are therefore more susceptible to Pt dissolution."must be corrected to "This is ascribed to the higher Pt surface energies of the smaller particles, which are therefore more susceptible to Pt dissolution".
