H-Type 3-Port Jacketed Photoelectrochemical Cell with Quartz Window

The H-Type 3-Port Jacketed Photoelectrochemical (PEC) Cell is a dual-compartment, membrane-separated reactor designed for controlled light-driven electrochemistry. An optically transparent quartz window enables illumination of photoelectrodes, while the H-type architecture physically separates anolyte and catholyte to minimise product crossover and enable cleaner mechanistic interpretation. Principle of operation A working photoelectrode is illuminated through the quartz window to generate charge carriers and drive interfacial redox reactions. The second chamber houses the counter electrode, and the compartments are separated by a replaceable ion-exchange membrane (e.g., proton exchange or anion exchange), supporting selective ion transport while limiting bulk mixing. A circulating water jacket stabilises temperature, improving kinetic reproducibility and helping manage exothermic or light-induced heating effects. Key features and materials High-purity borosilicate glass body for chemical resistance and easy cleaning Removable quartz optical window for high UV–Vis transmission and straightforward replacement Water-jacketed design for connection to a recirculating chiller or water bath Three-port configuration to support flexible electrode and gas-handling layouts (e.g., working, reference, gas inlet/outlet, sampling, or auxiliary feedthroughs) Membrane-separated chambers to enable differential electrolytes, pH gradients, or product isolation Sealed operation to support inert-gas purging and low-oxygen experiments Compatibility Suitable for standard three-electrode photoelectrochemistry with potentiostats/galvanostats (including EIS-capable systems), common reference electrodes, gas lines (N₂/Ar/CO₂), and interchangeable membranes. Pairs naturally with related ScienceGears categories such as potentiostats, electrochemical cells, Raman-SEC cells, and battery/energy test systems for integrated workflows. Typical applications Photoanode/photocathode screening (water splitting, oxygen evolution, hydrogen evolution) CO₂ reduction and solar fuels research with controlled gas atmospheres Semiconductor stability studies and light-intensity/temperature-dependence measurements Membrane selectivity and crossover evaluation under illumination Why choose ScienceGears ScienceGears supports Australia & New Zealand researchers with practical configuration guidance, membrane and accessory selection, and seamless integration with electrochemical instrumentation for reproducible PEC testing.
