Product Description
Gas Diffusion Photoelectrochemical Cell
(Photocatalytic Gas Diffusion Electrode Cell with Serpentine Flow Field)
Product Overview
The Gas Diffusion Photoelectrochemical Cell is a research-grade electrochemical reactor specifically engineered for photoelectrochemical and photocatalytic studies involving gas-phase reactants. The cell is designed around the gas diffusion electrode (GDE) concept, enabling efficient gas transport to the catalytic interface while simultaneously allowing controlled electrochemical bias and optical irradiation.
By integrating a serpentine gas flow field, the cell maximizes gas–catalyst contact time and ensures uniform gas distribution across the active electrode area. This makes it particularly suitable for advanced studies in photocatalytic CO₂ reduction, gas-phase photoelectrochemistry, and light-assisted electrocatalysis.
Unlike membrane-separated electrolyzers, this model is dedicated to gas diffusion operation only and is not intended for anodic–cathodic compartment separation. Its streamlined architecture minimizes internal resistance and simplifies experimental setup for fundamental and applied photocatalytic research.
Key Features
•Dedicated Gas Diffusion Photoelectrochemical Design Optimized exclusively for gas diffusion electrode operation; not intended for cathode–anode separation.
•Serpentine Gas Flow Path Enhances residence time of reactant gases behind the GDE, improving mass transfer and reaction efficiency.
•Optical Accessibility for Photocatalysis Designed to enable direct illumination of gas diffusion electrodes, supporting photo-assisted electrochemical reactions.
•Broad Electrode Compatibility Supports carbon cloth, carbon paper, metal foam electrodes, reticulated vitreous carbon (RVC), and other porous GDE structures.
•Research-Grade Construction Robust sealing and precision machining ensure reproducible results and stable long-term operation.
•Humidified Gas Compatibility Can be paired with an external gas humidifier for experiments requiring controlled gas humidity.
Cell Structure and Working Principle
The cell operates by delivering reactant gas through a serpentine flow channel located behind the gas diffusion electrode. Gas permeates through the porous GDE and reaches the catalyst–electrolyte–solid triple-phase boundary, where photoelectrochemical reactions occur under applied potential and external illumination.
The simplified single-functional design reduces dead volume and electrical resistance, making it ideal for kinetic studies, catalyst screening, and light-assisted gas conversion experiments.
