Three-Chamber H-Cell (Triple H-Cell) – Gas-Tight Electrochemical Cell

Three-compartment control for cleaner electrochemistry

A Three-Chamber H-Cell (Triple H-Cell) is designed for experiments where anode, cathode, and an intermediate/conditioning chamber must be physically separated while still allowing selective ionic transport. The compartments are assembled in a modular H-cell format and can be configured with ion-exchange membranes (e.g., cation/anion-exchange films) between chambers to minimise cross-over, prevent product re-oxidation/reduction, and stabilise sensitive reference conditions.

How it works

In operation, the working and counter reactions occur in separate chambers, while the third chamber can act as a buffer zone (e.g., for ion exchange, mediator chemistry, or staged separation). Membrane interfaces support controlled ion migration while restricting bulk mixing, enabling higher-fidelity electrolysis and mechanistic studies.

Key features and materials

• Borosilicate glass chambers for chemical resistance and solvent compatibility
• PTFE lids + O-ring sealing for gas-tight, leak-resistant assembly
• Multiple electrode and gas ports for three-electrode measurements and purging under inert atmosphere
• Scalable volumes (commonly in the tens to hundreds of mL per chamber) for screening through preparative studies
• Configurable for Nafion/Fumasep and related separators, plus custom porting on request
  
  

Compatibility and typical set-ups

Compatible with standard three-electrode configurations (Ag/AgCl or Hg/HgO reference; Pt/graphite counter; custom working electrodes) and routine connection to potentiostats/galvanostats for CV, CA/CP, and bulk electrolysis.

Typical applications

• Electrodialysis and ion-exchange research
• Electro-organic synthesis with reduced cross-contamination
• CO₂ reduction or selective catalysis requiring separated anodic/cathodic products
• Membrane screening and transport studies (crossover, permselectivity)
