Claim 3:
4. The process according to claim 3, 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 ABQ3-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, characterized in that the one or more lower-valent cations are selected from Ca, Sr, or Mg;
one or more ABQ3-perovskites with A bivalent 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, characterized in that the one or more lower-valent cations are magnesium, scandium, yttrium, neodymium or ytterbium; and
one or more A2B2O7-pyrochlores with A trivalent cation and B tetra-valent cation being at least partially substituted in A position with one or more lower-valent cations and comprise at least one of Sn, Zr and Ti in B position, characterized in that the one or more lower-valent cations are Ca or Mg.
