H type Sealed Jacketed Photoelectrochemical cell

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 Why ScienceGears ScienceGears Australia supports researchers with fit-for-purpose PEC hardware plus the surrounding workflow—potentiostats, light sources, gas handling accessories, membranes, and in-situ spectroscopy options (e.g., Raman-SEC cells where appropriate)—to help you build a reliable, publishable photoelectrochemistry platform.
