“…5 The MEA comprises a proton exchange membrane (PEM) sandwiched between two catalyst layers (CLs) and two gas diffusion layers (GDLs). 6 The conventional configuration of the MEA exhibits several limitations, such as hindered mass transportation, catalyst aggregation, and membrane degradation. [7][8][9] Consequently, it is essential to investigate novel MEA structures that can enhance the performance and surmount the catalyst polarization corrosion problem.…”
