In this work, we prepared SrFe<sub<0.9</sub<Ti<sub<0.1</sub<O<sub<3−δ</sub<–Ce<sub<0.8</sub<Sm<sub<0.2</sub<O<sub<1.9</sub< composite cathodes with different layers (1×, 3×, 5×, 7×, and 9× layer). The microstructural and electrochemical performance of each cell was then explored through scanning electron microscopy and electrochemical impedance spectroscopy (EIS). EIS analysis showed that the area-specific resistance (ASR) decreased from 0.65 Ωcm<sup<2</sup< to 0.12 Ωcm<sup<2</sup< with the increase in the number of layers from a 1× to a 7×. However, the ASR started to slightly increase at the 9× layer to 2.95 Ωcm<sup<2</sup< due to a higher loss of electrode polarization resulting from insufficient gas diffusion and transport. Therefore, increasing the number of cathode layers could increase the performance of the cathode by enlarging the active area for the reaction up to the threshold point.

EIS analysis showed that the area-specific resistance (ASR) decreased from 0.65 Ωcm<sup<2</sup< to 0.12 Ωcm<sup<2</sup< with the increase in the number of layers from a 1× to a 7×. However, the ASR started to slightly increase at the 9× layer to 2.95 Ωcm<sup<2</sup< due to a higher loss of electrode polarization resulting from insufficient gas diffusion and transport. Therefore, increasing the number of cathode layers could increase the performance of the cathode by enlarging the active area for the reaction up to the threshold point. area-specific resistance electrochemical impedance layered structures microstructures solid oxide fuel cell Organic chemistry Nurul Akidah Baharuddin verfasserin aut Mahendra Rao Somalu verfasserin aut Andanastuti Muchtar verfasserin aut In Molecules MDPI AG, 2003 27(2022), 8, p 2549 (DE-627)311313132 (DE-600)2008644-1 14203049 nnns volume:27 year:2022 number:8, p 2549 https://doi.org/10.3390/molecules27082549 kostenfrei https://doaj.org/article/edb5039b1ded4596bb84ed4433cad65f kostenfrei https://www.mdpi.com/1420-3049/27/8/2549 kostenfrei https://doaj.org/toc/1420-3049 Journal toc kostenfrei GBV_USEFLAG_A SYSFLAG_A GBV_DOAJ GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_39 GBV_ILN_40 GBV_ILN_60 GBV_ILN_62 GBV_ILN_63 GBV_ILN_65 GBV_ILN_69 GBV_ILN_70 GBV_ILN_73 GBV_ILN_95 GBV_ILN_105 GBV_ILN_110 GBV_ILN_151 GBV_ILN_161 GBV_ILN_170 GBV_ILN_206 GBV_ILN_213 GBV_ILN_224 GBV_ILN_230 GBV_ILN_285 GBV_ILN_293 GBV_ILN_602 GBV_ILN_2005 GBV_ILN_2009 GBV_ILN_2011 GBV_ILN_2014 GBV_ILN_2055 GBV_ILN_2111 GBV_ILN_4012 GBV_ILN_4037 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4249 GBV_ILN_4305 GBV_ILN_4306 GBV_ILN_4307 GBV_ILN_4313 GBV_ILN_4322 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4325 GBV_ILN_4338 GBV_ILN_4367 GBV_ILN_4700 AR 27 2022 8, p 2549

abstract	Cathode thickness plays a major role in establishing an active area for an oxygen reduction reaction in energy converter devices, such as solid oxide fuel cells. In this work, we prepared SrFe<sub<0.9</sub<Ti<sub<0.1</sub<O<sub<3−δ</sub<–Ce<sub<0.8</sub<Sm<sub<0.2</sub<O<sub<1.9</sub< composite cathodes with different layers (1×, 3×, 5×, 7×, and 9× layer). The microstructural and electrochemical performance of each cell was then explored through scanning electron microscopy and electrochemical impedance spectroscopy (EIS). EIS analysis showed that the area-specific resistance (ASR) decreased from 0.65 Ωcm<sup<2</sup< to 0.12 Ωcm<sup<2</sup< with the increase in the number of layers from a 1× to a 7×. However, the ASR started to slightly increase at the 9× layer to 2.95 Ωcm<sup<2</sup< due to a higher loss of electrode polarization resulting from insufficient gas diffusion and transport. Therefore, increasing the number of cathode layers could increase the performance of the cathode by enlarging the active area for the reaction up to the threshold point.

In this work, we prepared SrFe<sub<0.9</sub<Ti<sub<0.1</sub<O<sub<3−δ</sub<–Ce<sub<0.8</sub<Sm<sub<0.2</sub<O<sub<1.9</sub< composite cathodes with different layers (1×, 3×, 5×, 7×, and 9× layer). The microstructural and electrochemical performance of each cell was then explored through scanning electron microscopy and electrochemical impedance spectroscopy (EIS). EIS analysis showed that the area-specific resistance (ASR) decreased from 0.65 Ωcm<sup<2</sup< to 0.12 Ωcm<sup<2</sup< with the increase in the number of layers from a 1× to a 7×. However, the ASR started to slightly increase at the 9× layer to 2.95 Ωcm<sup<2</sup< due to a higher loss of electrode polarization resulting from insufficient gas diffusion and transport. Therefore, increasing the number of cathode layers could increase the performance of the cathode by enlarging the active area for the reaction up to the threshold point.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">area-specific resistance</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield
