1. A membrane comprising, in order, a first catalyst layer, an electronically and ionically conducting layer having a nanosized microstructure, and a second catalyst layer, wherein the electronically and ionically conducting layer is formed from an electrolyte material, a grain growth inhibitor and/or a grain boundary modifier,
wherein the electronically and ionically conducting layer comprises Ce1-xMxO2- δ(where M is selected from the group consisting of Ca, Sm, Gd, Sc, Ga and Y, and 0 ≦x≦1); wherein the grain growth inhibitor comprises an oxide selected from the group consisting of Sc2O3, VOx, TaOx, MnOx, NbOx, SrO, CaO, MgO, Bi2O3, LnOx, MgCr2O4, MgTiO3, CaAl2O4, LaAlO3, YbCrO3, ErCrO4, NiTiO3, NiCr2O4, metal carbides, metal nitrides, and mixtures thereof; and wherein the grain boundary modifier comprises an oxide selected from the group consisting of MnOx, VOx, MgCr2O4, CaCrxVyO4, SrCrxVyO4, YbCrO3, ErCrO4, NiTiO3, NiCr2O4, and mixtures thereof. |
