In　comparison　to　various　power　generating　devices/energy　conversion　systems,　solid　oxide　fuel　cell　(SOFC)　has　received　much　attention　due　to　its　remarkable　efficiency,　reliability　and　low　pollution.　Modified　pechini　method　is　used　to　synthesize　La0.7Sr0.3Ti0.1Fe0.6Ni0.3O3-δ　(LSTFN)　perovskite　material　and　is　utilized　as　cathode　and　anode　for　intermediate-temperature　symmetrical　solid　oxide　fuel　cell　(IT-SSOFC).　The　X-ray　diffractometer　(XRD)　patterns　reveals　perovskite　cubic　structure　with　single　phase　for　LSTFN.　The　maximum　conductivity　~318　Scm−1　is　obtained　for　LSTFN　in　air　at　a　temperature　of　700　°C,　but　is　decreased　with　further　increase　in　temperature　due　to　small　polaron　mechanism.　However,　the　conductivity　is　enhanced　up　to　~1.1　Scm−1　at　the　same　temperature　in　the　presence　of　dry　H2,　being　capable　to　be　utilized　both　as　anode　and　cathode.　Low　polarization　resistance　(Rp)　~0.047　(with　air)　and　0.201Ωcm2　(with　dry　H2)　is　exhibited　by　as　prepared　perovskite　material　at　a　temperature　of　800　°C.　The　fabricated　symmetrical　cell　maintains　good　stability　with　no　apparent　degradation　during　the　tested　hours　~300　in　air　and　~100　with　dry　H2.　©　2020　Elsevier　B.V.
