Gas Diffusion Electrochemical Cell (Three-Electrode System), Model: EC-GDE-1LC / EC-GDE-2LC

EC-GDE-1LC / EC-GDE-2LC Gas Diffusion Electrochemical Cell

A series of large-liquid-chamber, three-electrode gas diffusion electrochemical cells with serpentine gas flow fields for flow-phase electrochemical studies.

Product Overview

Designed for flow-phase electrochemical studies with gas diffusion electrodes, the Series combines a serpentine gas flow field with a large liquid chamber for controlled gas delivery and stable reaction conditions. The enlarged chamber improves electrolyte buffering and tolerance to flow and bubble disturbances. EC-GDE-1LC uses a single liquid chamber for general testing, while EC-GDE-2LC features dual membrane-separated chambers for independent electrolyte control on the working/reference and counter-electrode sides.

Key Features

Large Liquid-Phase Buffering
Enlarged liquid chambers improve electrolyte buffering and reduce sensitivity to short-term flow disturbances.

Controlled Gas Delivery
A serpentine gas flow field provides a defined pathway for reactant gas delivery to the gas diffusion electrode.

Flexible Chamber Configuration
EC-GDE-1LC uses a single liquid chamber, while EC-GDE-2LC adds membrane-separated dual liquid compartments.

Typical Applications

Gas-Diffusion Electrode Studies
Evaluating GDEs under controlled gas delivery and flow-phase electrochemical conditions.

Gas-Phase Electrocatalysis
Studying CO₂ reduction and other gas-involved electrochemical reactions under continuous-flow conditions.

Steady-State Electrolysis
Supporting long-duration testing with enhanced liquid-phase buffering and membrane-separated electrolyte environments (EC-GDE-2LC only).

Technical Specifications

Model Selection Guide

EC-GDE-1LC
The standard single-liquid-chamber configuration, combining a large liquid chamber with a serpentine gas flow field. Suitable for general gas diffusion electrode testing, flow-phase electrochemical studies, and experiments requiring a stable bulk electrolyte environment.

EC-GDE-2LC
A membrane-separated dual-liquid-chamber configuration that isolates the working/reference electrode side from the counter-electrode side. Suitable for experiments requiring independent catholyte and anolyte environments, membrane studies, and separated electrode reaction conditions.

Related Published Application

Liquid-Phase Buffering in CO₂ Flow Electrolysis
Martens et al. investigated a 10 cm² GDE CO₂ flow cell with a ~3 mL catholyte compartment and current densities up to ~1.2 A cm⁻². The limited in-cell electrolyte volume amplified heat and gas-evolution effects: at −0.8 A cm⁻², the catholyte temperature difference across the cell reached ~20 K, while bubble accumulation reduced electrode–electrolyte contact and increased cell resistance. Improving electrolyte conductivity and cooling reduced catholyte temperature by 8–12 K and extended the stable operating range, highlighting the importance of sufficient liquid-phase buffering and effective thermal/gas management in GDE flow electrolysis.
