Claim 5:
6. The process according to claim 5, characterized in that the mixed oxides being doped with one or more lower-valent cations are selected from the group consisting of:
one or more ABO3-perovskites with A and B tri-valent cations, being at least partially substituted in A position with one or more lower-valent cations and comprising at least one of Ni, Ga, Co, Cr, Mn, Sc, Fe and/or a mixture thereof in B position, and wherein said one or more lower-valent cations are selected from the group consisting of Ca, Sr, and Mg;
one or more ABO3-perovskites with A bi-valent cation and B tetra-valent cation, being at least partially substituted with one or more lower-valent cations in the B position occurs or with a mixture of different B elements in the B position and wherein the one or more lower-valent cations are selected from magnesium, scandium, yttrium, neodymium or ytterbium; and
one or more A2B2O7-pyrochlores with A tri-valent cation and B tetra-valent cation being at least partially substituted in A position with one or more lower-valent cation and comprising at least one of Sn, Zr and Ti in B position and wherein the one or more lower-valent cations are selected from Ca or Mg.
