The invention provides a solid electrolyte electrolytic cell membrane electrode. The membrane electrode includes an optimized layer, and the optimized layer can improve the operation efficiency and safety of the electrolytic cell, and is specifically realized by reducing the hydrogen content in the anode. The preparation process of the optimized layer structure is simple and easy to implement, and can be realized by common spraying, screen printing, blade coating and other processes. The assembly location of the optimization layer can be between the anode catalytic layer and the membrane, or outside the anode catalytic layer, or mixed with either or both of the anode catalytic layers. The principle is that the optimized layer quenches the hydrogen on the anode side through a chemical reaction to reduce the hydrogen content. By optimizing the layer-to-membrane electrode optimization, the gas purity and hydrogen concentration on the anode side of the electrolytic cell can be achieved beyond the explosion limit without significantly increasing the system cost and auxiliary equipment, achieving the effect of improving efficiency and safe operation. |
