When Raman laser light is focused through the transparent window onto the gas diffusion electrode (GDE), reactant gases are able to diffuse through, providing insights into the electrochemical reactions and morphological changes on the electrode surface.\u003c\/p\u003e\n\u003cp\u003eGas diffusion Raman electrochemical cells are made of three chambers: a working electrode chamber, a counter electrode chamber, and a gas chamber. These three chambers are physically well-separated from one another, with the counter electrode chamber next to the working electrode chamber and the gas chamber directly under it. The contact of the gas chamber with the working electrode chamber is through the gas diffusion electrode, while the contact of the counter electrode chamber with the working electrode chamber is through the ion exchange membrane. In the top and centre of the working electrode chamber sits the quartz window. The gas chamber employs a serpentine flow path, which significantly increases the contact time between the gas and the gas diffusion electrode, resulting in a more efficient catalytic reaction during Raman spectroscopy.\u003c\/p\u003e\n\u003cp\u003eThe electrochemical cells feature a PEEK body for excellent chemical resistance and a built-in gas channel in the cathode chamber for gas diffusion in order to support flow systems and injection-based filling. The three-compartment structure is held together with a screw-sealed membrane interface and is detachable for easy access and cleaning. The working electrode chamber is compatible with gas diffusion and planar electrodes, and the chamber accommodates both the GDE and reference electrode.\u003c\/p\u003e\n\u003cp\u003eGas diffusion Raman electrochemical cells have applications in the fields of fuel cells, battery electrode\/electrolyte interfaces, electrocatalytic water splitting and hydrogen evolution reactions (HERs), oxygen reduction\/evolution reactions (ORRs\/OERs), and carbon dioxide reduction reactions (CO2RRs). Real-time in-situ Raman spectroscopy is particularly helpful as a way of providing information on structural and morphological changes during operation.\u003c\/p\u003e\n\u003cdiv
