The　electrocatalytic　activity　of　oxygen　reduction　reaction　on　the　cathodes　of　solid　oxide　fuel　cells　tends　to　be　severely　degraded　due　to　the　Cr　poisoning　effect　ascribed　to　the　use　of　a　Fe-Cr　alloy　interconnect.　Here,　a　hybrid　catalyst　coating　consisting　of　BaCe0.8Gd0.2O3-delta　and　BaCO3　is　developed　on　(La0.8Sr0.2)(0.95)MnO3+delta　(LSM)　cathodes　to　enhance　the　electrocatalytic　performance　and　chromium　tolerance.　The　hybrid　catalyst　coated　LSM　cell　shows　an　excellent　peak　power　density　of　1.31　W　cm(-2)　at　750?degrees　C,　dramatically　higher　than　0.22　W　cm(-2)　of　bare　LSM　cell.　The　hybrid　catalyst　coating　also　significantly　enhances　the　operational　stability　of　LSM　cathodes　under　accelerated　chromium　poisoning　conditions.　The　hybrid　catalyst　coating　on　the　outermost　electrode　surface　preferentially　reacts　with　the　Cr2O3　scale　layer　on　the　Fe-Cr　interconnect　to　form　conductive　BaCrO4,　and　meanwhile　the　hybrid　catalyst　coating　inside　the　electrode　is　inert　to　the　gaseous　Cr　species,　leading　to　remarkable　Cr　tolerance　of　the　cathode.　This　work　sheds　light　on　the　rational　design　of　an　efficient　and　durable　LSM　based　cathode　for　solid　oxide　fuel　cells.
