摘要：

The effect of dopant valence on oxygen desorption and oxygen permeability of SrCo0.4Fe0.5M0.1O3-delta (M = Ni, Al and Zr) mixed-conducting oxides were investigated in detail by O-2-TPD and oxygen permeation measurement. The SrCo0.4Fe0.5M0.1O3-delta for M = Fe, Ni, Al and Zr were denoted as SCF, SCFN, SCFA and SCFZ, respectively. O2-TPD analysis revealed that the amount of a oxygen desorption decreased with increasing the valance of doped metal elements (SCFN > SCFA approximate to 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.
