Abstract：

Proton　exchange　membrane　fuel　cells　(PEMFCs)　are　playing　irreplaceable　roles　in　the　construction　of　the　future　sustainable　energy　system.　However,　the　insufficient　performance　of　platinum　(Pt)-based　electrocatalysts　for　oxygen　reduction　reaction　(ORR)　hinders　the　overall　efficiency　of　PEMFCs.　Engineering　the　surface　strain　of　catalysts　is　considered　an　effective　way　to　tune　their　electronic　structures　and　therefore　optimize　catalytic　behavior.　In　this　paper,　insights　into　strain　engineering　for　improving　Pt-based　catalysts　toward　ORR　are　elaborated　in　detail.　First,　recent　advances　in　understanding　the　strain　effects　on　ORR　catalysts　are　comprehensively　discussed.　Then,　strain　engineering　methodologies　for　adjusting　Pt-based　catalysts　are　comprehensively　discussed.　Finally,　further　information　on　the　various　challenges　and　potential　prospects　for　strain　modulation　of　Pt-based　catalysts　is　provided.
