The invention relates to an electrochemical synthesis device based on a high-temperature high-pressure electrolysis technology, wherein a solid oxide electrolytic cell of the electrochemical synthesis device is provided with an electrolyte layer, and a cathode layer and an anode layer which are respectively positioned at two opposite sides of the electrolyte layer, wherein catalyst components required by the synthesis of chemicals or oils are respectively loaded in the cathode layer and the anode layer so as to couple the reaction of high-temperature electrolysis water vapor and/or carbon dioxide and the high-temperature electrocatalytic reaction, thereby preparing high-pressure hydrogen, synthesis gas and oxygen and directly synthesizing the chemicals or the oils; the gas control system is used for controlling the composition, flow and pressure of the gas reactant and the gas product; the thermal management system is used for monitoring and controlling the ambient temperature and the electrode temperature of the solid oxide electrolytic cell. According to the electrochemical synthesis device based on the high-temperature high-pressure electrolysis technology, water and/or carbon dioxide are/is used as raw materials, intermediate products such as hydrogen, carbon monoxide or synthesis gas are prepared through high-temperature high-pressure electrolysis, and high-value chemicals or oil products are further synthesized. |
