Herein, we develop a mesh\u2010island confinement strategy to construct a ternary PtCoSn catalyst via alternating atomic layer deposition. In this design, Co preferentially occupies low\u2010coordination Pt sites, while Sn is selectively enriched on the nanoparticle surface and carbon support. Upon reduction, a PtCoSn alloy core is formed and stabilized by a surface SnO\u2010based mesh and support\u2010confined islands. This architecture enables the catalyst to achieve superior oxygen reduction reaction\u00a0activity and significantly enhanced stability compared to conventional binary alloys by suppressing transition metal dissolution and inhibiting nanoparticle migration. The membrane electrode assembly achieves a peak power density of 1.46\u00a0W cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    and a mass activity of 0.73 A mg\n                    <jats:sub>Pt<\/jats:sub>\n                    <jats:sup>\u22121<\/jats:sup>\n                    , with only 14.4% performance degradation after 30\u00a0000 accelerated durability cycles.
