Oxygen electrode supporting type solid oxide electrolytic tank and preparation method thereof
The invention discloses an oxygen electrode supporting type solid oxide electrolytic tank and a preparation method thereof. According to the method, firstly, a composite casting technology is adopted, oxygen electrode supporting layer slurry, oxygen electrode active layer slurry and electrolyte layer slurry are subjected to layer-by-layer casting in sequence, an oxygen electrode supporting layer/oxygen electrode active layer/electrolyte layer composite membrane biscuit is obtained, then the dried composite membrane biscuit is cut into square pieces, and the square pieces are co-fired to obtain the oxygen electrode supporting type half cell. And finally, printing a fuel electrode in a silk-screen printing manner, and combining to prepare the oxygen electrode supported solid oxide electrolytic cell. An organic composite tape casting method is used, the process is simple, the oxygen electrode of the prepared oxygen electrode supporting type SOEC is firmly combined with an electrolyte interface, higher three-phase interface oxygen partial pressure can be borne, the problem of performance degradation caused by layering and cracks of an electrolytic tank is effectively solved, operation is stable, and the service life is longer.
本发明公开了一种氧电极支撑型固体氧化物电解池及其制备方法。所述方法先采用复合流延工艺，依次将氧电极支撑层浆料、氧电极活性层浆料、电解质层浆料逐层流延，获得氧电极支撑层/氧电极活性层/电解质层复合膜素坯，然后将干燥的复合膜素坯切割成方片，共烧得到氧电极支撑型半电池，最后通过丝网印刷方式印刷燃料极，组合制成氧电极支撑型固体氧化物电解池。本发明使用有机复合流延方法，工艺简单，制得的氧电极支撑型SOEC的氧电极和电解质界面结合牢固，可承受更高的三相界面氧分压，有效改善电解池因出现分层、裂纹而导致的性能衰减问题，运行稳定且寿命更长。
