H type Sealed Jacketed Photoelectrochemical cell

Overview

The H-Type Sealed Jacketed Photoelectrochemical (PEC) Cell is a dual-chamber, gas-tight electrochemical reactor designed for quantitative photoelectrode testing under controlled temperature and atmosphere. Its H-cell architecture physically separates anodic and cathodic compartments using an ion-exchange membrane, helping prevent product crossover and enabling cleaner product analysis during solar fuels research.

Working Principle

Light enters through a quartz optical window to illuminate a photoelectrode (typically the working electrode). A potentiostat controls potential/current in a standard two- or three-electrode configuration, while the sealed design supports degassing and controlled reactant/product handling. The outer jacket circulates thermostated fluid to stabilise temperature—critical for reproducible kinetics, gas solubility, and long-duration stability testing.

Key Features and Materials

• Dual-chamber H-cell with membrane slot for Nafion®, AEMs, CEMs, or BPMs (application-dependent)
• Quartz window (UV–Vis transparent) for solar simulator or LED illumination
• Jacketed body for heating/cooling via recirculating bath
• Sealed ports / feedthroughs for working, counter, and reference electrodes
• Gas inlet/outlet options for N₂/Ar purging and product sampling
• Typical working volumes are available in multiple sizes (commonly tens to hundreds of mL per cell, depending on model)
  
  

Compatibility and Applications

Ideal for use with potentiostats/galvanostats and compatible reference electrodes (e.g., Ag/AgCl, Hg/HgO) and counter electrodes (Pt mesh/foil). Common applications include:

• Photoelectrochemical water splitting (HER/OER)
• CO₂ reduction (photo-assisted or hybrid PEC)
• Semiconductor photoanode/photocathode screening
• Stability, photocorrosion, and Faradaic efficiency studies
