ABSTRACT:
A mixed ionic conductor with an ion conductive oxide has a perovskite structure of the formula Baa(Ce1-bM1b)LcO3-α, whereinM1is at least one trivalent rare earth element other than Ce;L is at least one element selected from the group consisting of Zr, Ti, V, Nb, Cr, Mo, W, Fe, Co, Ni, Cu, Ag, Au, Pd, Pt, Bi, Sb, Sn, Pb and Ga;with 0.9≦a≦1;0.16≦b≦0.26;0.01≦c≦0.1;and (2+b−2a)/2≦α<1.5.Such a mixed ionic conductor has not only the necessary conductivity for electrochemical devices such as fuel cells, but also superior moisture resistance.
