H-type Electrolyte Circulation Electrochemical Cell

H-type Electrolyte Circulation Electrochemical Cell

Dual-Chamber Design · Continuous Electrolyte Flow · Gas–Liquid Electrochemistry

Product Overview

The FrankLab H-type Electrolyte Circulation Electrochemical Cell is a sealed, dual-chamber electrochemical reactor designed for long-duration electrolysis, electrolyte refresh, and flow-assisted electrochemical studies.

Unlike static H-cells, this system integrates dedicated electrolyte inlet and outlet ports on both chambers, enabling continuous circulation, concentration control, and enhanced mass transfer—critical for mechanistic studies, durability testing, and scale-up validation.

This platform is widely used in CO₂RR, water splitting, redox flow evaluation, electrosynthesis, and experiments requiring membrane separation with controlled electrolyte renewal.

Structural Design & Configuration

True H-Type Dual Chamber

•Left chamber: Working electrode compartment

•Right chamber: Counter electrode compartment

•Central membrane clamp region (ion-exchange membrane / separator)

Electrolyte Circulation System

•Independent inlet + outlet ports on each chamber

•Compatible with peristaltic pumps or syringe pumps

•Supports closed-loop or open-loop circulation

Gas Management

•Dedicated gas inlet & outlet on each chamber

•Enables independent gas atmospheres (CO₂ / Ar / N₂ / O₂)

Available Volumes

✔ Symmetric volumes ensure stable hydrodynamics and ion transport
✔ Custom asymmetric volumes available upon request

Technical Specifications

Key Advantages

•True Electrolyte Circulation Control
Continuous electrolyte refresh eliminates concentration drift, pH gradients, and product accumulation.

• Stable Long-Term Operation
Ideal for hours-to-days electrolysis, catalyst durability testing, and steady-state studies.

• Membrane-Separated Architecture
Supports Nafion®, AEMs, BPMs, porous separators, and custom membranes.

• Independent Gas & Liquid Management
Each chamber can operate under different gas and electrolyte conditions.

• Research-Grade Sealing & Modularity
All ports sealed independently; components are easy to assemble, clean, and reconfigure.

·FrankLab | Note

This H-type circulation cell is not a generic glassware product—it is an electrochemical research platform.
Every port, seal, and interface is designed to support reproducibility, long-term stability, and mechanistic clarity.

If your experiment involves time, flow, gas, or membranes, static cells are the bottleneck.
This system removes that bottleneck.
