Solid-State Electrolyte Electrochemical Cell (Three-Electrode System) Model: QG-20-2

Description

The QG-20-2 has been enhanced with the addition of a reference electrode. The reference electrode chamber has a board thickness of 3mm.The overall design of the solid-state electrolyte cell incorporates a sandwich structure, establishing a gas-solid interface. It utilizes a solid electrolyte in place of liquid electrolyte, preventing the introduction of anions/cations and facilitating the direct production of high-purity liquid solutions.

Features:

• Bipolar Plates with Serpentine Gas Flow Channels: 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.
