Product Description

Product Overview
The Observable Gas Diffusion Electrode (GDE) Electrolyzer Cell is a research-grade, modular electrochemical reactor specifically engineered for gas-involved electrochemical reactions, including CO₂ reduction (CO₂RR), gas-phase electrocatalysis, and advanced interface studies.
The cell combines a transparent observation design with a precision-machined PEEK modular architecture, allowing researchers to directly visualize electrode behavior while maintaining excellent chemical resistance, sealing reliability, and experimental flexibility. It is designed to bridge the gap between fundamental mechanism studies and engineering-oriented electrolyzer evaluation.
This platform is particularly suitable for researchers who need real-time observation, controlled gas–liquid–solid interfaces, and repeatable flow-assisted electrochemical operation.

Core Design Philosophy
Unlike conventional closed electrolyzers, this GDE cell emphasizes:
•Observability – direct visual access to the reaction zone
•Configurability – modular stack allowing rapid structural changes
•Reproducibility – fixed geometries for reliable comparison across experiments
•Compatibility – supports common GDE materials, membranes, and tubing standards
The result is a versatile experimental tool that can be used both for mechanistic in-situ studies and performance benchmarking of GDE systems.

Key Features & Advantages
  1. Transparent Observation Window
Enables direct visual monitoring of:
•Gas bubble formation and transport
•Flooding or drying of the GDE
•Interfacial wetting behavior
•Catalyst layer stability during operation
Particularly valuable for operando studies and failure mechanism analysis.
  1. Modular PEEK Stack Architecture
•All structural components are fabricated from high-performance PEEK:
•Excellent chemical resistance (acidic, alkaline, neutral electrolytes)
•High mechanical strength and dimensional stability
•Electrically insulating, minimizing parasitic currents
Layer-by-layer assembly allows:
•Fast disassembly and cleaning
•Easy replacement of electrodes, membranes, or spacers
•Custom thickness or geometry adjustments on request
  1. Optimized Reaction Chamber Geometry
Compact chamber size (20 × 5 × 3 mm) ensures:
•Well-defined mass transport conditions
•Reduced electrolyte volume
•High sensitivity to interfacial changes
Controlled anode–cathode distance (3 mm) minimizes ohmic losses while maintaining safe separation.
  1. Designed for Gas Diffusion Electrodes
Fully compatible with:
•Carbon paper / carbon cloth GDEs
•Catalyst-coated GDLs
•Custom-prepared GDE assemblies
Supports both gas-side feeding and flow-assisted electrolyte operation.
  1. Flow-Compatible Tubing Interface
Standard 3 mm PTFE tubing:
•Chemically inert
•Low gas permeability
•Easy integration with mass flow controllers, peristaltic pumps, or syringe pumps

Why Choose This Cell
From an engineering perspective, this GDE electrolyzer cell is not just a “test fixture” but a research platform. It allows teams to see what is actually happening inside the electrolyzer—something most conventional cells hide.
For PIs, PhD researchers, and electrochemical engineers, this translates to:
•Faster troubleshooting
•Stronger experimental evidence
•Clearer structure–performance correlations
•Data that stands up to peer review and scale-up discussions
