“…The most significant change is the decrease of the LF contribution for the CY cell under negative polarization (SOEC conditions), as a consequence of the optimized gas diffusion within the Ni-YSZ support. Positive impacts of using calcined YSZ in developing a porous YSZ microstructure for conversion to an anode or cathode upon infiltration has been previously shown by the authors1415161819212728. When cell infiltration for the purpose of improving the catalytic activity or the electronic/ionic conductivity (or both) of the anode is planned, an anode with larger pore size and higher porosity (~50%) than TY is desirable (due to pore clogging during infiltration).…”

“…The effectiveness of using calcined YSZ in the development of a porous structure for infiltration of nickel1415 or LSBT16 anodes as well as LSM1718 or Nd nickelate19 cathodes has been previously shown by the authors. Despite many studies on the effect of nickel particle size and content on anode microstructure and thus performance, there is a lack of information in the literature regarding the effect of using processed YSZ in the conventional nickel-YSZ anode on electrochemical performance.…”

“…It is shown that the MWCNTs showed enhancing effect on cell performance, which results in further decrease of activation polarization from ~1.2 Ω cm 2 to ~ 0.85 Ω cm 2 . Previous study in the literature ascribed the phenomenon of R 1 to charge transfer and that of R 2 to concentration polarization 19. After the decoration of CNTs, the value of R 1…”

“…With 40% of Sr sites occupied by La, a proportion of Ti 4+ is reduced to Ti 3+ to maintain the charge balance , leading to an increase in both electronic and ionic conductivities. Moreover, the substitution of Sr with Ba (LSBT) can further improve the ionic conductivity , . However, the catalytic activity of this catalyst is insufficient to provide a satisfactory performance compared to metallic catalysts.…”
