Abstract

This thesis explores scaling Cu–Pt near-surface alloys and PtxY alloys as ORR catalysts for PEM fuel cells, aiming for high ECSA (≥50 m²Pt g⁻¹Pt). A H₂-promoted Cu deposition method enabled large-scale CuML–Pt/C synthesis but faced size and cell design limits. For PtxY/C, a carbodiimide-assisted synthesis produced high-surface-area Ptshell/Pt₃Ycore catalysts, tested in RDE and PEMFC. Results reveal challenges in upscaling and stability, guiding next-gen ORR catalyst design.
