简介目录

2026年气体扩散层市场规模估计为22亿美元，预计2033年将达到176亿美元。预计2026年至2033年，该市场将以24.3%的复合年增长率成长。

分析范围		分析详情
基准年	2025	市场规模（2026 年）	22亿美元
效能数据	2020-2024	预测期	2026-2033
预测期（2026-2033 年）复合年增长率	24.30%	预计金额（2033 年）	176亿美元

气体扩散层（GDL）是一种纤维状多孔介质，主要功能有两个：一是将反应气体均匀分布到电极表面，二是实现电极与外部电路之间的电子传输。这些层由细碳纤维製成，碳纤维是一种多孔疏水材料。纤维厚度为250–400 μm，孔径为4–50 μm。气体扩散层也必须起到支撑电解质的作用，其结构必须能够排放可能抑制反应的水分。气体扩散层（GDL）是任何聚合物电解质膜（PEM）燃料电池的关键组件，主要负责气体和水的传输。 GDL由两层组成：大孔基底（MPS）和微孔层（MPL）。 MPS毗邻气体流动路径，通常允许气体通过碳纸或碳布扩散，并起到收集电流的作用。 MPL通常用于降低催化剂层（CL）和气体扩散层（GDL）之间的接触电阻。

市场动态

碳基材料是气体扩散层（GDL）结构的主要选择。碳是一种很有前景的质子交换膜（PEM）燃料电池组件材料，具有优异的导电性、透气渗透性、韧性和耐久性。碳纸或碳布用于GDL的多用途表面结构（MPS）。由于碳纤维之间存在空隙，碳布呈现两种不同的孔径分布。

由于铁和铜等多孔金属在各种工程应用中得到应用和开发，而这些应用正在显着增加，包括质子交换膜燃料电池，因此预计气体扩散层市场在预测期内将保持稳定成长。

金属基板在生物医学和能源运输等众多产业中具有结构和功能应用价值。基板低密度、开放结构中的高渗透性、高能量吸收和大比表面积使其具有优异的导电性和导热性，以及卓越的耐腐蚀性。

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.
