High-performance PrBaCo2O5+δ–Ce0.8Sm0.2O1.9 composite cathodes for intermediate temperature solid oxide fuel cell

GdBaCo2O5+δ–Sm0.2Ce0.8O1.9 composite cathodes for intermediate temperature SOFCs

“…Its Rp value was 1.39 cm 2 at 500 • C, meanwhile the value was 7.26 cm 2 for pure GBCO cathode. In addition, the performance of GBCO-SDC was better than many other composite cathodes at low temperature range, for example, PrBaCo 2 O 5+ı -Ce 0.8 Sm 0.2 O 1.9 composite cathode [26]. Fig.…”

Investigation of GdBaCo 2−x Fe x O 6−δ ( x = 0, 0.2) – Ce 0.8 Sm 0.2 O 2 composite cathodes for intermediate temperature solid oxide fuel cells

“…This observation is in agreement with data reported in Refs. [5,14,16,18,20] for composites consisting of double perovskites RBaCo 2 O 6Àd (R ¼ Pr, Sm, Gd) and CeO 2 -based solid electrolyte. Such change of the ASR with SDC content enables improvement of the electrochemical characteristic of cathodes based on the double perovskite GBC(F02) as well as decreasing working temperature of IT-SOFC.…”

Improved oxygen permeability of Ce0.8Sm0.2O2−–PrBaCo2O5+ dual-phase membrane by surface-modifying porous layer

“…1(a). This elongates the oxygen ion diffusion distance in pure PBCO layer and hence retards the oxygen permeation process [17]. Considering the isotropic feature of cubic structured SDC, PBCOeSDC porous layer is expected to shorten the oxygen ion diffusion distance and thereby accelerate the oxygen permeation process, as depicted in Fig.…”
