“…4), predominantly p-type electronic, is sufficiently close to the literature results [27,28]. The estimated apparent activation energy for the total conductivity is 12.2 F 0.2 kJ/mol (Table 3), also in good agreement with the literature (13.5 kJ/mol [28] (Fig.…”

“…The thermal expansion coefficient of Ce 0.8 Gd 0.2 O 2 À d averaged at 300 -1270 K was reported to be 12.5 Â 10 À 6 K À 1 [26], while the corresponding value for La 0.8 Sr 0.2 Fe 0.8 Co 0.2 O 3 À d was found equal to 14.8 Â 10 À 6 K À 1 [27] and 15.4 Â 10 À 6 K À 1 [28]. Along with experimental uncertainty and possible effects of ceramic microstructure on thermal expansion, this difference is due to the narrower temperature range used in the present work.…”

“…When the cobalt element in B-site is completely replaced by the iron element, the total conductivity decreases to $ 20 S cm À 1 , which is similar to the values reported by Chen et al [55]. Other researchers also found that the total conductivity of La 0.8 Sr 0.2 Co 1 À x Fe x O 3 À δ decreases with the increase of iron doping amount [56]. For the dual-phase materials, the fluorite oxide is the main phase, and its volume fraction is high, up to 70 vol%.…”

“…Isso ocorre devido a vários fatores, como a geometria da célula [40] e as mudanças causadas nos eletrodos devido as condições de operação da célula [39]. [42]. Esse alto valor de coeficiente de expansão térmica inviabiliza a utilização dessa composição em célula a combustível de óxido sólido, devido a grande diferença em relação ao coeficiente de expansão térmica da zircônia-ítria (material geralmente usado como eletrólito).…”
