Electrolyte-supported IT-SOFC with LSCF–SCFN composite cathode

Ruddlesden Popper oxides of LnSr3Fe3O10−δ (Ln = La, Pr, Nd, Sm, Eu, and Gd) as active cathodes for low temperature solid oxide fuel cells

“…Recently, the development of new cathode materials with mixed electronic and ionic conductivity (MEIC) has been considered to promote the oxygen migration at intermediate temperature. [1][2][3][4][5][6] Layered perovskites, e.g. La 2 NiO 4 6,7 and Sr 3Àx -La x Fe 2Ày Co y O 7 (0.3 # x # 0.6, 0 # y # 1.5) 8,9 have received much attention owing to the excess oxygen in their structure which contributes to oxide ion conductivity.…”

Overview of Approaches to Increase the Electrochemical Activity of Conventional Perovskite Air Electrodes

“…For the preparation of the LSCF-based electrodes, compositions with ionic conductors were used, such as YSZ [411,412], YSZ with GDC10 [413], GDC10 [160,336,407,[414][415][416][417][418] GDC [110,120,171,[417][418][419][420][421], Nd x Gd 0.15 Ce 0.85 − x O 2 − δ (NGCOx) [166], SDC [114,127,162,184,185,416,[422][423][424][425][426], Ce 0.8 Zr 0.2 O 2 − δ [427], BZYb [177], BCZYYb [178,181], BCZY [185], BCZY15 [186], La 2 Ce 2 O 7 (LCO) [185], LSGM [428,429], as well as with the MIEC materials Bi 0.3 Sr 0.7 Co 0.3 Fe 0.7 O 3 − δ [172], La 0.94 Ni 0.6 Fe 0.4 O 3 (LNF94) [340], Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3 − δ [430], SrCo 0.2 Fe 0.6 Ni 0.2 O 3 − δ [431]. As in the case of the LSM-based composites, the LSCF-based composite electrodes can be prepared by conventional mixing…”

Battery and solid oxide fuel cell materials

“…Swierczek has investigated the performance of composite cathodes consisting of La 0.8 Sr 0.2 Co 0.2 Fe 0.8 O 3-y and SrCo 0.2 Fe 0.6 Ni 0.2 O 3-y in cells with CGO electrolytes and Ni-yttria stabilized zirconia (YSZ) anodes. 99 A large (60-70%) increase in the maximum power density was observed for the cathode with 20 wt% SrCo 0.2 Fe 0.6 Ni 0.2 O 3-y , suggesting promise for this cathode composite.…”
