Solid-State Electrolyte Electrochemical Cell (Two-Electrode System) Model: QG-20-1

Description

The solid-state electrolyte cell adopts a sandwich structure, establishing a gas-solid interface. It utilizes a solid electrolyte in place of liquid electrolyte, eliminating the introduction of anions/cations and directly achieving the preparation of high-purity liquid product solutions.

Features:
● Electrode bodies 1 and 3 serve as bipolar plates with inner serpentine gas flow channels, effectively enhancing the concentration of gaseous reactants on the catalyst surface to achieve high current density.
● Between electrode bodies 1 and 2, a double-layer structure comprising an anion membrane (dioxide material) and a gas diffusion layer (loaded with anode catalyst) is employed to realize the gas-solid interface and anion transport (Note: hot pressing is required for sufficient contact). Similarly, between electrode bodies 2 and 3, a double-layer structure with a cation membrane (Nafion115) and a gas diffusion layer (loaded with cathode catalyst) is used to achieve the gas-solid interface and cation transport (Note: hot pressing is required for sufficient contact).
● Electrode body 2 is the core component of the solid-state electrolyte cell, featuring a built-in 3mm thick square (4cm2) hollow layer. This layer can be filled with molded solid electrolyte to replace the liquid electrolyte, enabling the direct preparation of liquid fuels. The solid electrolyte primarily consists of highly conductive polymer or porous ceramics. The use of pure water aims to carry away the liquid product, promoting the shift of the reaction equilibrium to the right and obtaining impurity-free product aqueous solutions.
● Substances generated in electrode body 1 and electrode body 3 pass through their respective membranes and react in intermediate electrode body 2, producing products carried away by flowing pure water.
