“…8 In additions, it shows a quite smooth and good adhesion between different layers. This is analogous to the results of literature report, 19),27) a 45¯m thick electrolyte performs high power density after sintering at 1450°C. So far, it is noticed that power density of anode supported cells was reported in some literatures.…”

Electrical Properties Of Indium And Yttrium-Doped Barium Cerate-Based Compounds For Use As Ceramic Fuel Cell Electrolytes

“…3b) can be explained by the porous morphology of the sample. Research on BCI30 with more compact morphology has yielded more promising electrical conductivity results [12,13]. Nevertheless, higher conductivity values at the respective temperatures have been determined for BaCeO 3 samples doped with yttrium [2][3][4][5][6][7][8]12].…”

“…It has been determined that barium cerate doped with 30%at. indium (BCI30) exhibit better stability against CO 2 [12,13].…”

Effect of indium content on the properties of BaSn0.5Y0.5−xInxO2.75 proton conductor

“…Recently, the rare earth oxides were used as a second dopant for barium cerates and zirconates to improve their sinterability and electrical conductivity [21][22][23][24][25][26][27][28]. It was reported that the indium as a dopant is favorable to the stability and sinterability of proton-conducting perovskites, such as an indium dopant enhances the stability and sinterability of BaCeO 3 in CO 2 atmosphere [24,25], and the indium as a second dopant can improve the sinterability of BaZr 0.9 Y 0.1 O 3 À δ [26].…”
