Research Summary

A gas diffusion layer (GDL) is a crucial component in electrolyzers, particularly in proton exchange membrane (PEM) electrolyzers, which are used to produce hydrogen through the process of water electrolysis. The GDL is positioned between the bipolar plate and the catalyst-coated membrane. Its primary functions include facilitating the uniform distribution of gases (hydrogen and oxygen) to and from the catalyst layer, ensuring efficient gas transport, and providing structural support to the membrane-electrode assembly. Typically made from porous materials such as carbon paper or carbon cloth, the GDL is designed to be both electrically conductive and highly permeable to gases. This permeability allows for the effective removal of produced gases while maintaining the necessary moisture balance within the electrolyzer. The performance, efficiency, and durability of the electrolyzer are significantly influenced by the properties of the GDL, making it a vital element in the overall system.
