La0.6Sr0.4Fe0.8Cu0.2O3− perovskite oxide as cathode for IT-SOFC

Gasification and Syngas Reforming of City Waste Papers for Solid Oxide Fuel Cells

“…The power density and IV for a single cell are shown in Figure 6. The open circuit voltage (OCV) was 0.98 V, and the maximum power density was 326 mWcm -2 for H2 fuel at 800°C, which was close to the value of 400 mWcm -2 for a previous work which used LaSrFeCuO 3-δ as the cathode and testing up to 800°C [15].…”

Novel cobalt-free cathode material (Nd0.9La0.1)2(Ni0.74Cu0.21Al0.05)O4+δ for intermediate-temperature solid oxide fuel cells

“…ASRs values of 0.266, 0.121, 0.070, and 0.048 Ω cm 2 are obtained at 650, 700, 750, and 800 1C in air, respectively. These ASR values are much lower than those for other cobalt-free cathodes reported by various groups, such as La 2 NiO 4 þ δ [24], Pr 2 Ni 0.6 -Cu 0.4 O 4 [25], SrFe 0.9 Nb 0.1 O 3 À δ [26], La 0.6 Sr 0.4 Fe 0.8 Cu 0.2 O 3 À δ [27], and Ba 0.5 Sr 0.5 Zn 0.2 Fe 0.8 O 3 À δ [21]. The lower ASR value of the NLNCA cathode shows high catalytic activity for oxygen reduction at intermediate temperatures.…”

“…7 shows the current-voltage (I-V) and currentpower (I-P) curves obtained at different temperatures with pure hydrogen as fuel and ambient air as oxidant. It can be seen that the maximum power densities of the cell are 176, 295, 399, and 521 mW cm À 2 at 650, 700, 750, and 800 1C, respectively, similar to those of the cells of Ni-SDC/SDC/ LSFCu (LSFCu: La 0.6 Sr 0.4 Fe 0.8 Cu 0.2 O 3 À δ ) with the thickness of the SDC electrolyte of $ 300 mm [27]. This shows that NLNCA is a very promising cathode candidate for IT-SOFCs using SDC electrolyte.…”

Evaluation of double perovskite Sr2FeTiO6−δ as potential cathode or anode materials for intermediate-temperature solid oxide fuel cells

“…Recently, many "cobalt-free" cathode materials are reported, which show high compatibility with other cell components and good long term stability as well as favorable electrochemical performance [28][29][30][31][32][33][34].…”
