A mixed ionic conductor with an ion conductive oxide has a perovskite structure of the formula Baa(Ce1-bM1b)LcO3-alpha, wherein M1 is 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<=alpha<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.
