The purpose of this treatise is focused on the electrolyte part of solid oxide fuel cell (SOFC), and the structure refinement, electrical analysis and XANES spectra were be used in this research. The oxide materials in this research include (Y2-xLix)Ti2O7 -aLiO0.5 (a = 0, 2 and 4, x = 0 - 0.11; a = 1 and 3, x = 0.070) with abbreviation of YLT-aL, (Gd2-xLix)Ti2O7- aLiO0.5 (a = 0, 2 and 4, x = 0 - 0.15, a = 1 and 3, x = 0.100) with abbreviation of GLT-aL, Ln2Zr2O7 (Ln = Eu, Ho and Yb) with abbreviation of LZ, Ln2(ZrTi)O7 (Ln = Eu, Ho and Yb) with abbreviation of LZT and LnDC ((Ln0.2Ce0.8)O1.9) (Ln = La, Sm, Gd and Gd + Y). The LZ, LnZT and LnDC series were chosen to make composite electrolyte materials with LNCO carbonate mixture (The molar ratio of Li2CO3 : Na2CO3 = 1 : 1) and the abbreviations are LZ-C, LZT-C and LnDC-C, respectively.
The YLT-2L (x = 0.070) has the highest total conductivity of 4.42(4) x 10-4 S |
