Component maps for (a) the carbon support, (b) the ionomer and (c) Pt, derived from fitting a full C 1s stack of a cathode catalyst layer in the gas diffusion layer structure (region selected in Fig. 5e[link]). (d) Re-scaled colour composite of the Pt (red), ionomer (green) and carbon support (blue) component maps. Scale bars are 2 µm; grey intensity bars represent thickness in nanometres.
