N-doped atomically-thin carbon layer in PNAC-o-Pt3Fe/C shields Pt atoms from ionomer poisoning, increases the number of active sites, and improves O2 permeability and long-term stability. Note: This model is schematic and a relatively reasonable structure has been chosen and this image was created using 3D Max and PS software.
