Abstract：

Solid　oxide　cells　(SOCs)　are　emerging　devices　for　efficient　energy　storage　and　conversion.　However,　during　SOC　operation,　gaseous　chromium　(Cr)　species　released　from　Fe-Cr　alloy　interconnect　can　lead　to　Cr　deposition　and　poisoning　of　air　electrodes,　causing　substantial　degradation　in　electrochemical　performance　and　compromising　the　longterm　stability　of　SOCs.　This　mini-review　examines　the　mechanism　of　Cr　deposition　and　poisoning　in　air　electrodes　under　both　fuel-cell　and　electrolysis　modes.　Furthermore,　emphasis　is　placed　on　the　recent　advancements　in　strategies　to　mitigate　Cr　poisoning,　offering　insights　into　the　rational　design　and　development　of　active　and　Cr-tolerant　air　electrodes　for　SOCs.　©　2025　Science　Press.　All　rights　reserved.
