We could visualize the three-dimensional distribution and two-dimensional depth map of the amount, oxidation state (valence), Pt2+ elution, detachment, and aggregation of Pt species and the formation of carbon voids, where the change and movement of the Pt species in the cathode catalyst layer during the AGEX cycles did not proceed exceeding the 1 μm region. It is very different from the case of an ADT (an accelerated durability test between 0.6-1.0 VRHE)-degraded MEA. We discuss the spatiotemporal behavior of the AGEX degradation pro
