•The ultrafine L11-PtCu intermetallic compound nanoparticles were synthesized.•They showed high resistance to phosphate poisoning.•It exhibits a superior peak power density of 800.5 mW cm−2 in 160℃ H2-O2 HT-PEMFC. In high-temperature proton exchange membrane fuel cells (HT-PEMFC), phosphate anions a...
