Product Description
Product Overview
The Acrylic Gas Diffusion Electrode (GDE) Electrolyzer Cell is a research-grade, fully observable electrochemical flow cell engineered for gas–liquid–solid electrochemical systems. Built with a transparent acrylic body, this cell allows researchers to directly visualize interfacial phenomena during operation—an ability that conventional opaque metal flow cells cannot provide.
The platform is specifically designed for CO₂ electroreduction (CO₂RR) but is equally suitable for gas-fed hydrogen evolution (HER), oxygen evolution (OER), and other membrane-separated gas electrolysis reactions. Its modular construction enables rapid reconfiguration, making it ideal for both fundamental mechanistic studies and engineering-oriented electrolyzer evaluation.
This cell is widely adopted in university laboratories, national research institutes, and industrial R&D centers focusing on advanced electrocatalysis and electrolyzer development.
Core Design Concept
This Acrylic GDE Electrolyzer Cell is built around four non-negotiable research requirements:
•True Gas Diffusion Architecture Dedicated gas chamber feeding reactants directly to the catalyst layer through a gas diffusion electrode.
•Full Optical Observability Transparent acrylic walls enable real-time visualization of flooding, bubble dynamics, and electrolyte distribution.
•Membrane-Separated Electrolysis Independent control of cathode and anode environments for realistic electrolyzer operation.
•Highly Modular Construction Interchangeable plates and spacers support fast iteration and customization.
Cell Architecture & Working Principle
Three-Chamber Configuration
Gas Chamber
•Dedicated chamber for gaseous reactants (CO₂, N₂, Ar, O₂, etc.)
•Gas contacts the catalyst layer through a user-supplied gas diffusion electrode (GDE)
•Enables precise control of gas flow rate and residence time
Cathode Chamber
•Liquid electrolyte chamber adjacent to the GDE
•Primary reaction zone for gas-involved electrochemical processes
•Transparent walls allow direct observation of:
GDE wetting and flooding
Gas bubble nucleation and detachment
Catalyst layer stability
Anode Chamber
•Separated from cathode by an ion-exchange membrane
•Supports independent anolyte chemistry and OER operation
Separation Logic
•Gas chamber ↔ Cathode chamber: Gas diffusion electrode (GDE)
•Cathode chamber ↔ Anode chamber: Ion-exchange membrane
This architecture closely mirrors practical electrolyzer systems while preserving laboratory-scale accessibility.
