Probing the Transport Properties, Electrophoretic Deposition, and Electrochemical Performance of La_2–xSm_xCe₂O₇ Ceramics for IT-SOFCs

Dual-phase Yb-doped La2Ce2O7 materials for fuel flexible SOFCs

“…The intensity as well as area of the designated peaks were considered for calculation. 32 The Raman spectra typically show four strong peaks at about 578, 450, 361, and 254 cm −1 . The oxygen vacancy (O1) and F 2g are represented by the first two wide mode peaks at 578 and 450 cm −1 , respectively.…”

“…The observed phenomenon may be attributed to the destabilization of the cell and electronic leakage in the electrolyte at elevated operating temperatures, specifically at 700 and 650 °C. 32 Nevertheless, it is noteworthy that the cell may exhibit stability over prolonged operation, as evidenced by the findings of DiGiuseppe, 55 who reported a great reduction in the polarization resistance of LSCF-based cathode after a duration of 1050 h. Furthermore, in order to comprehensively comprehend the polarization contribution of the electrodes in the cell with utmost precision, the utilization of the distribution of relaxation time (DRT) method was implemented. 56,57 Fig.…”

“…29 A few attempts have been made towards the deposition of LCO-based electrolytes. 30–32 However, the investigation of EPD coatings for Yb-doped LCO has not been explored.…”
