This research aims to develop highly efficient Pt-based intermetallic catalysts for fuel cells with improved activity and durability.
Developed L12-Pt3Mn nanoparticles supported on Mn–N–C carbon.
Evaluated the electrocatalytic properties through oxygen reduction reaction (ORR) testing.
Assessed performance in proton exchange membrane fuel cells (PEMFCs) under H2/air conditions.
Achieved a peak power density of 1.15 W cm−2 in PEMFCs.
Post 30,000 cycles, voltage loss at 0.8 A cm−2 was only 19 mV.
Demonstrated superior catalytic performance compared to conventional catalysts.
