Furthermore, the dependence of the stability of carbon-supported Pt-based nanoalloys not only on intrinsic but also on non-intrinsic factors, should be addressed in both RDE and MEA. For instance, in addition to the effect of temperature, the impact of the potential window on the stability of carbon-supported Pt-based nanoalloy electrocatalysts has also recently been shown and extensively described. Namely, it has been clear for some time that an increase in UPL strongly affects the stability of carbon-supported Pt-nanoalloys, both in terms of carbon support corrosion and metal dissolution. Moreover, in terms of metal dissolution, in our recent work it has been shown that at a constant high temperature (75 o C),
