Dual confinement strategy for Pt–Co intermetallic electrocatalysts with superior durability in proton exchange membrane fuel cells

Key Points

• To develop a novel dual confinement strategy for creating highly ordered PtCo electrocatalysts that resist metal dissolution.
• Utilized a dual confinement strategy for the synthesis of L1 0 -PtCo electrocatalysts.
• Conducted performance testing over 30,000 cycles in proton exchange membrane fuel cells.
• Achieved near-zero performance loss after 30,000 cycles.
• Demonstrated superior durability compared to traditional electrocatalysts.
