Fig. 6: Temperature profiles from system model simulations in countercurrent mode.

Results of thermodynamic performance where the operating temperatures are compared for BCZM (dashed lines), CeO2 (solid lines) and LCMA6464 (dashed-dot lines) with reduction temperatures shown in red and oxidation temperatures in blue. Conditions explored: (a) δred = 0.04, δox = 0.005, θmax = 0.1, (b) δred = 0.045, δox = 0.01, θmax = 0.05, (c) δred = 0.04, δox = 0.005, θmax = 0.01, and (d) δred = 0.04, δox = 0.005, θmax = 0.05 (including LCMA in dot-dashed lines83 for comparison). Common parameters: nN2/nH2 = 3, pO2, min = 10 Pa (0.00001 bar) and θmin = 10-3.
