CNB-12-EC-GDE-SE1
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

Model Selection Guide
QG-20-1
The standard configuration for high-purity liquid-product generation and routine solid-electrolyte research. 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.

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.
