Introduction to Gas Diffusion Layer (GDL)<\/h2>\n<p>The Gas Diffusion Layer (GDL) is a critical component in proton exchange membrane fuel cells (PEMFCs) and other electrochemical energy devices. Positioned between the catalyst layer and the flow field plate, the GDL serves multiple essential functions: it ensures uniform distribution of reactant gases (hydrogen and oxygen\/air) across the catalyst surface, facilitates the removal of product water, conducts electrons and heat, and provides mechanical support to the membrane electrode assembly (MEA). Typically made from carbon-based materials such as carbon paper or carbon cloth, the GDL is treated with a microporous layer (MPL) to optimize water management and electrical conductivity. Without a high-performance GDL, fuel cell efficiency, durability, and power density are severely compromised.<\/p>\n<h2 id=\"toc-33d70b994506a677d948f70d93f45137\">2.
