In-situ Raman Spectroelectrochemical Cell

Three-Chamber H-Type Gas Diffusion Cell with Serpentine Flow Field
Operando Raman Spectroscopy · Gas–Liquid–Solid Interfaces · Advanced Electrocatalysis

Product Overview
The FrankLab C031-S In-situ Raman Spectroelectrochemical Cell is a high-end research platform engineered for real-time spectroscopic and electrochemical investigation of gas-involved reactions at well-defined interfaces.
The working electrode is positioned directly beneath a large-area, high-transmittance sapphire optical window, allowing Raman and optical systems to directly monitor surface structure evolution, reaction intermediates, and catalyst reconstruction under precisely controlled electrochemical conditions.
Unlike conventional two-chamber spectroelectrochemical cells, the C031-S adopts a true three-chamber H-type architecture, consisting of a gas chamber, working electrode chamber, and counter electrode chamber. These compartments are separated by user-supplied gas diffusion electrodes (GDEs) and ion-exchange membranes, enabling clean phase isolation and accurate operando analysis of gas-electrochemical processes.
A serpentine gas flow field integrated into the gas chamber significantly enhances gas residence time and distribution uniformity, ensuring efficient gas–catalyst interaction and superior mass transport compared with flat or straight-channel designs.
