Gas Diffusion Electrochemical Cell (Solid-Electrolyte Series), Model: EC-GDE-SE Series

EC-GDE-SE Series Gas Diffusion Electrochemical Cell A three-chamber solid-electrolyte cell series for high-purity liquid production, potential studies, flow-field development, and optical observation. Product Overview The EC-GDE-SE Series comprises four three-chamber solid-electrolyte electrochemical cells for high-purity aqueous liquid-product generation. Their sandwich architecture combines gas-fed electrode chambers, ion-exchange membranes and a central solid-electrolyte chamber, where ionic products recombine and are collected by flowing pure water. Available configurations support two- or three-electrode measurements, central flow-field development, optical observation, and photo-assisted reaction studies. Key Features Solid-Electrolyte Product Recovery A pure-water stream collects high-purity aqueous products from the central solid-electrolyte chamber with minimal electrolyte contamination. Three-Chamber Gas-Solid Architecture Gas-fed chambers, ion-exchange membranes, and catalyst-loaded gas-diffusion layers create controlled gas-solid reaction interfaces. Research-Specific Configurations Models support two- or three-electrode testing, central flow-field development, optical observation, and photo-assisted reactions. Typical Applications High-Purity Liquid-Product Generation High-purity aqueous product collection for solid-electrolyte electrolysis research. Electrode-Potential & Mechanistic Studies Three-electrode measurements for catalyst evaluation and reaction-mechanism studies. Flow-Field Development & Mass-Transfer Studies Central flow-field design for mass-transfer analysis and device optimization. In Situ Optical & Photo-Assisted Studies Optical access for in situ observation, photocatalysis, and photoelectrochemical studies.

Its two-electrode design and open central chamber are suitable for electrolyte evaluation and device testing. QG-20-2 For experiments requiring individual electrode-potential monitoring. A dedicated reference-electrode chamber enables three-electrode measurements for catalyst evaluation and mechanistic studies. QG-20-3 For flow-field development and mass-transfer studies. A serpentine flow field in the central chamber supports device optimization and technology validation. QG-20-4 For experiments requiring optical access to the cathode chamber. It combines a central serpentine flow field with a high-transmittance quartz window for in situ observation, photocatalytic studies, and photoelectrochemical experiments. Related Published Application High-Efficiency H₂O₂ Electrosynthesis in a Solid-Electrolyte Cell Dong et al. used a two-electrode, three-chamber solid-electrolyte flow cell to investigate direct H₂O₂ electrosynthesis via O₂ reduction. At 2.5 V, the system operated at approximately 100 mA cm⁻² for 8 h, producing a 3400 ppm H₂O₂ solution with approximately 85% Faradaic efficiency. Capabilities Relevant to the QG-20 Series Separates anode, solid-electrolyte, and cathode regions with ion-exchange membranes for selective ion transport. Collects central-chamber aqueous products directly via a flowing pure-water stream. Supports continuous electrolysis with gas-flow channels and central water flow. Application Studies Application studies using this model are currently underway. Note: The referenced study used a two-electrode, three-chamber solid-electrolyte cell with a configuration comparable to the QG-20 Series. It is included solely as a related application example and does not confirm that any QG-20 Series model was used.
