Thin solid oxide cell |
摘要 |
The present invention relates to a thin and in principle unsupported solid oxide cell, comprising at least a porous anode layer, an electrolyte layer and a porous cathode layer, wherein the anode layer and the cathode layer comprise an electrolyte material, at least one metal and a catalyst material, and wherein the overall thickness of the thin reversible cell is about 150 μm or less, and to a method for producing same. The present invention also relates to a thin and in principle unsupported solid oxide cell, comprising at least a porous anode layer, an electrolyte layer and a porous cathode layer, wherein the anode layer and the cathode layer comprise an electrolyte material and a catalyst material, wherein the electrolyte material is doper zirconia, and wherein the overall thickness of the thin reversible cell is about 150 μm or less, and to a method for producing same. The present invention further provides a thin separation membrane, comprising at least a porous anode layer, a membrane layer comprising a mixed conducting material and a porous cathode layer, wherein the anode layer and the cathode layer comprise the mixed conducting material and a catalyst material, and wherein the overall thickness of the thin separation membrane is about 1050 μm or less. |

1. A thin solid oxide cell, comprising at least a porous anode layer, an electrolyte layer and a porous cathode layer, wherein the anode layer and the cathode layer comprise an electrolyte material, at least one metal and a catalyst material, and wherein:
the overall thickness of the thin cell is about 100 μm or less; the electrolyte material of the anode layer and the cathode layer is selected from the group consisting of doped ceria, gallates and proton conducting electrolytes; the at least one metal is selected from the group consisting of a FeCrMx alloy, and a NiCrMx alloy, wherein Mx is selected from the group consisting of Ni, Ti, Ce, Mn, Mo, W, Co, La, Y, Zr, Al, and mixtures thereof; the anode layer and the cathode layer are multilayer structures comprising at least two layers each, one of the layers in each of the anode and cathode layer being in direct contact with the electrolyte layer; and the at least two layers of the cathode and the anode have a different thermal expansion coefficient, wherein the respective layers directly in contact with the electrolyte layer have: i) an identical thermal expansion coefficient prior to impregnation which is larger than the thermal expansion coefficient of the electrolyte layer; and ii) a thermal expansion coefficient larger than the thermal expansion coefficient of the respective second layers of the electrodes. |
