Abstract

The effect of dopant valence on oxygen desorption and oxygen permeability of SrCo_0.4Fe_0.5M_0.1O_3-δ (M = Ni, Al and Zr) mixed-conducting oxides were investigated in detail by O₂-TPD and oxygen permeation measurement. The SrCo_0.4Fe_0.5M_0.1O_3-δ for M = Fe, Ni, Al and Zr were denoted as SCF, SCFN, SCFA and SCFZ, respectively. O₂-TPD analysis revealed that the amount of α oxygen desorption decreased with increasing the valance of doped metal elements (SCFN > SCFA ≈ SCF > SCFZ). The oxygen permeation flux at the temperature higher than 1148 K decreased in the order of SCFN > SCF > SCFZ > SCFA. Single activation for oxygen permeation was observed for SCFZ oxide and the activation energies of SCF and SCFA change at around 1073 K, while the change temperature of SCFN was about 1173 K.
