氣體擴散層（GDL）是一種纖維狀多孔介質，主要功能有兩個：一是將反應氣體均勻分佈到電極表面，二是實現電極與外部電路之間的電子傳輸。這些層由細碳纖維製成，碳纖維是一種多孔疏水材料。纖維厚度為250–400 μm，孔徑為4–50 μm。氣體擴散層也必須起到支撐電解質的作用，其結構必須能夠排放可能抑制反應的水分。氣體擴散層（GDL）是任何聚合物電解質膜（PEM）燃料電池的關鍵組件，主要負責氣體和水的傳輸。 GDL由兩層組成：大孔基底（MPS）和微孔層（MPL）。 MPS毗鄰氣體流動路徑，通常允許氣體通過碳紙或碳布擴散，並起到收集電流的作用。 MPL通常用於降低催化劑層（CL）和氣體擴散層（GDL）之間的接觸電阻。

市場動態

碳基材料是氣體擴散層（GDL）結構的主要選擇。碳是一種很有前景的質子交換膜（PEM）燃料電池組件材料，具有優異的導電性、透氣滲透性、韌性和耐久性。碳紙或碳布用於GDL的多用途表面結構（MPS）。由於碳纖維之間存在空隙，碳布呈現兩種不同的孔徑分佈。

由於鐵和銅等多孔金屬在各種工程應用中得到應用和開發，而這些應用正在顯著增加，包括質子交換膜燃料電池，因此預計氣體擴散層市場在預測期內將保持穩定成長。

金屬基板在生物醫學和能源運輸等眾多產業中具有結構和功能應用價值。基板低密度、開放結構中的高滲透性、高能量吸收和大比表面積使其具有優異的導電性和導熱性，以及卓越的耐腐蝕性。

The gas diffusion layers (GDL) are a fibrous porous media with two primary functions: uniform distribution of reactive gases on the electrode surfaces and electron transfer to and from the external electrical circuit. They are made of thin carbon fibers, a porous and hydrophobic material. The thickness of these fibers is between 250 and 400 μm, and the perforations or pores available are 4 to 50 μm in size. These gas diffusion layers must also serve as a support for the electrolyte, and their structure must allow water to escape, which would prevent the reaction from occurring. Gas diffusion layer (GDL) is a crucial component which is mainly responsible for the gas and water transport in any polymer electrolyte membrane (PEM) fuel cell. GDL is made up of two major layers: macroporous substrate (MPS) and microporous layer (MPL). MPS is subsequent to the gas flow field and it generally works by providing gas diffusion through carbon paper or carbon cloth and collecting the current. MPL is commonly used to reduce the contact resistance between the catalyst layer (CL) and the gas diffusion layer (GDL).

Market Dynamics

Carbon-based materials are mostly preferred for the construction of the GDL. Carbon is a favorable material that is capable of providing good electrical conductivity, gas permeability, elasticity and durability for PEM fuel cell components. Carbon paper or carbon cloth is used in the content of MPS of the GDL. Dual pore size distribution can be seen for the carbon cloth due to the voids between the carbon fibers.

The gas diffusion layer market is expected to register stable growth over the forecast period, owing to the use and development of porous metals such as iron and copper among others, in various engineering applications such as proton exchange membrane fuel cells that have increased substantially.

The metal substrates offer structural and functional applications in a wide range of industries such as biomedical applications and energy transportation. The metals substrates offer low density, high permeability in open structures, high energy absorption, and large specific surface area, and thereby linked with good electrical and thermal conductivity, and are corrosion resistant.
