Layered　perovskite　oxides　are　well　known　to　possess　significant　electronic,　magnetic　and　electrochemical　properties.　Herein,　we　highlight　a　novel　layered　perovskite　PrBaMn1.5Fe0.5O5+delta　(PBMFO)　as　electrodes　of　symmetrical　solid　oxide　fuel　cells　(SSOFCs).　The　layered　PBMFO　shows　high　electrical　conductivity　of　112.5　and　7.4　S　cm(-1)　at　800　degrees　C　in　air　and　5%　H-2/Ar,　respectively.　The　single　cell　with　PBMFO　symmetric　electrodes　achieves　peak　power　density　of　0.54　W　cm(-2)　at　800　degrees　C　using　humidified　hydrogen　as　fuel.　Moreover,　PBMFO　electrodes　demonstrate　good　redox　stability　and　high　coking　tolerance　against　hydrocarbon　fuel.　(C)　2016　Elsevier　B.V.　All　rights　reserved.
