Introduction

This cell combines two classical analytical techniques such as electrochemistry and Raman spectroscopy, to obtain in-situ chemical information about the reactions taking place during an electrochemical experiment. 

Key Features 

1. Dual-Compartment Design with Ion-Exchange Membrane

• Physically separates anode and cathode compartments
• Prevents mixing of reactants and products
• Minimizes cross-talk between electrode reactions
• Enables more accurate electrocatalytic measurements

2. Independent Control of Reaction Environments

• Different electrolytes or pH conditions can be used in each compartment
• Allows precise tuning of:
  • pH
  • Ionic strength
  • Specific ion composition
• Ideal for systematic electrocatalysis studies

3. Reduced Side Reactions and Interference

• Limits unwanted reactions common in single-compartment cells
• Membrane blocks interfering species from reaching the electrode
• Improves reliability and selectivity of results

4. Enhanced Stability and Durability

• Prevents electrolyte mixing
• Reduces electrode fouling and degradation
• Ensures stable long-term operation

5. Raman Spectroscopy Compatibility

• Sapphire optical window enables in situ Raman analysis
• Laser focuses through a thin electrolyte layer (3.25 mm optical path)
• Suitable for real-time monitoring of electrode processes

6. Modular and Versatile Design

• Supports both 2-electrode and 3-electrode configurations
• Bottom-loading sample holder with magnetic or screw mount
• Tantalum foil provides reliable electrical contact

7. Flexible Electrode Integration

• Compatible with thin-film working electrodes on rigid or flexible substrates
• Optional adapter supports 6 mm diameter electrodes

  Electrode Adapter For Raman ECFC

• Enables use of various electrode types, including:
  • Disk electrodes
  • Rods (e.g., graphite)
  • Metal foils and meshes
  • Carbon-based materials

8. Expandable to Gas Diffusion Electrode (GDE) System

• Convertible to GDE configuration with optional gas compartment
• Allows use of gas diffusion electrodes for advanced applications

9. Chemically Resistant Construction

• Built from inert materials (PEEK, fluorocarbons)
• Compatible with:
  • Aqueous electrolytes (FKM O-rings)
  • Organic solvents (FFKM O-rings)

10. Gas-Tight System

• Prevents contamination from oxygen and moisture
• Supports inert gas purging via external electrolyte reservoir
• Suitable for sensitive electrochemical experiments

Application Note

This cell can be used to track kinetic phenomena such as the near-surface proton concentration changes during oxidation and reduction reaction at working electrode. It can be also used to identify materials such as carbon, metal oxides, polymers and electrolytes, and to determine their structure and distribution. Various metals are suitable for this cell as auxiliary electrode including Platinum, Gold and Silver. 
The use of Raman Electrochemical Flow H-Cell with an ion-exchange membrane provides a more controlled and reliable platform for studying electrocatalysis, allowing researchers to investigate fundamental mechanisms and optimize catalytic performance with greater precision. For troubleshooting instruction see the redox.me blog post
