Solid electrolyte electrochemical cell (three-electrode system) Model: QG-20-1
As shown in the figure, the solid state electrolytic cell adopts a sandwich structure as a whole to build a gas-solid interface, and uses a solid electrolyte to replace the electrolyte
The introduction of Yin/cation directly realizes the preparation of aqueous solution of high purity liquid product.
The specific structure is as follows:
1、 Cell body 1 and 3 are bipolar plates with a snake-like airflow channel inside, which effectively improves the concentration of gas reactants on the catalyst surface to achieve high current density.
2、 the anionic film (anionic material) and gas diffusion layer (supported anode catalyst) are used between the cell body 1 and 2 to achieve the gas-solid interface and anion transfer (note: hot press molding is required to ensure full contact). A two-layer structure of cationic film (nafion115) and gas diffusion layer (loaded cathode catalyst) is adopted between cell 2 and cell 3 to realize gas-solid interface and cation transfer(Note: need to use hot press molding to ensure full contact).
3、 The cell body 2 is the core component of the solid-state electrolytic cell, with a 3mm thick square (4cm2) hollow layer built in, which can be filled with solid electrolyte instead of electrolyte to achieve direct preparation of liquid fuel. Solid electrolyte is mainly polymer with good electrical conductivity Or porous ceramics, the purpose of pure water is to take the liquid product away, prompting the reaction balance to shift to the right and get free of impurities.
An aqueous solution of the product. The substances produced in cell No. 1 and cell No. 3 pass through their respective membranes and combine to form products in cell No. 2 in the middle and are carried away by flowing pure water.
Solid electrolyte electrochemical cell (three-electrode system) Model: QG-20-2
On the basis of QG-20-1, a reference electrode was added, the thickness of the reference electrode chamber was 3mm, and the solid state electrolytic cell as a whole adopted sandwich structure to construct the gas-solid interface.
Solid electrolyte was used to replace the electrolyte, avoiding the introduction of negative/cation, and directly realized the preparation of high-purity liquid product aqueous solution.
Solid electrolyte electrochemical cell (snake channel system) Model: QG-20-3
As shown in the figure, the second plate is improved on the basis of QG-20-1 and the snake channel is added. The solid state electrolytic cell adopts the sandwich structure as a whole to construct the gas-solid interface and use solid electrolyte to replace the electrolyte, avoiding the introduction of Yin/cation to directly achieve the preparation of high-purity liquid product aqueous solution.
Solid electrolyte electrochemical cell (visualization) Model: QG-20-4
As shown in the figure, an upgrade on the basis of QG-20-3 adds a visual high transmittance quartz window in the cathode chamber, which can be used for optical observation of the working electrode of the cathode chamber or to increase light.
