In-situ Raman CO2RR MEA Cell with Interchangeable Optical Windows

Description

The In-situ Raman CO2RR MEA Cell with Interchangeable Optical Windows is designed for real-time Raman investigation of membrane electrode assembly (MEA) electrolysers during electrochemical CO2 reduction. In this configuration, the catalyst-coated electrode is positioned close to the optical window so the Raman probe can collect spectra from the active reaction zone while the cell operates under gas-flow and current load. This approach helps researchers correlate cell voltage, current density, catalyst state, and reaction intermediates during CO2RR and related electrocatalytic studies. In-situ Raman is widely used to probe surface-bound intermediates and catalyst transformations, while quartz and sapphire are both established window materials for Raman-compatible electrochemical cells.

Key Design Features

• Interchangeable optical windows, including sapphire and quartz, to suit different laser wavelengths, optical preferences, and chemical environments
• MEA-style architecture for gas-fed CO2 electrolysis and operando catalyst evaluation
• Titanium cell body for robust mechanical strength, corrosion resistance, and suitability in demanding electrochemical environments
• Approximate 4 cm² flow-field area for practical laboratory-scale screening and comparative studies
• Short specimen-to-window distance of less than 5 mm to support efficient signal collection and optical access
• Gold-plated electrical terminals and compact flow-cell layout for integration into advanced electrochemistry test systems

Key Design Features

This Raman MEA cell is well suited for use with confocal Raman microscopes, potentiostats, galvanostats, electrochemical impedance systems, gas handling accessories, and CO2 electrolysis test stations. It is relevant for CO2RR catalyst development, gas diffusion electrode studies, membrane screening, operando mechanistic research, and broader spectroelectrochemistry workflows across catalysis, energy conversion, and materials science. Researchers can use interchangeable windows to balance optical transmission, hardness, and chemical durability for the chosen experiment.
