Carbon paper is an advanced two-dimensional material made from carbon fibers. As a key fundamental material, it has a wide range of applications. In the hydrogen energy field, it can be used as a gas diffusion layer material for fuel cells and a diffusion layer material for proton exchange membrane electrolyzers. In the energy storage field, it can be used as an electrode material for flow batteries. The main functions of hydrogen-energy carbon paper include uniform gas diffusion, electron conduction, thermal management, and water transport, thereby improving the power density, efficiency, and durability of fuel cells and electrolyzer stacks. Typical product forms are sheets or rolls, with a thickness of approximately 100–400 μm and a porosity of generally 70%–80%. The surface hydrophobic/hydrophilic properties and conductivity can be optimized according to application requirements to balance gas/liquid transport performance and mechanical strength. The core technologies include carbon fiber network structure design, thermal carbonization/graphitization treatment, and surface functional coatings to achieve stable operation of high-power-density fuel cells, proton exchange membrane electrolyzers (PEM Electrolyzers), and some flow battery systems. Hydrogen-energy carbon paper is an indispensable basic material in PEMFC, PEM electrolyzer, and flow battery systems. The core raw materials for carbon paper production are carbon fiber, polyvinyl alcohol resin, and phenolic resin. Carbon paper production processes are divided into wet and dry processes. The wet process is a mature technology, used by manufacturers such as Toray and SGL Carbon. Wet-processed carbon paper exhibits good uniformity and a dense structure, making it a commonly used method for high-performance carbon paper in fuel cells abroad. Dry-process carbon paper production is a rapidly developing technology in recent years. This method uses air as a medium, employing an airflow web-forming process to create the base paper, followed by subsequent processes such as sizing, drying, and carbonization. Its characteristics include a high carbon fiber content and high product strength.

In 2025, the global production of Hydrogen Energy Carbon Paper was approximately 11.394 million square meters, with a unit price of approximately US$57.14-142.85 per square meter, an average price of approximately US$71.42 per square meter, and a gross profit margin of approximately 9.38%-19.74%.

The essence of the hydrogen energy carbon paper industry lies in providing efficient and stable gas diffusion and electron conduction media for fuel cells and hydrogen electrolyzers. As a key basic material within membrane electrode assemblies (MEAs), carbon paper achieves uniform distribution of hydrogen and oxygen through its porous carbon fiber network, while also undertaking electron conduction, thermal management, and water management functions, significantly improving the power density and lifespan of fuel cell stacks. The industry has clear boundaries, mainly covering PEMFCs, PEM electrolyzers, and some flow battery systems, providing core material support for downstream electric transportation, stationary energy storage, and portable hydrogen energy devices.

From a supply perspective, global hydrogen energy carbon paper production is characterized by high technological barriers and regional concentration. North America, Europe, and East Asia are the core production areas, with major suppliers exhibiting differentiated product offerings in terms of thickness, porosity, conductivity, and surface treatment methods.

From a demand structure perspective, downstream growth primarily stems from the expansion of transportation, stationary energy storage, and portable hydrogen energy equipment. Global hydrogen energy policy initiatives and the increasing penetration rate of fuel cell vehicles, coupled with the continued rise in demand from energy storage and industrial hydrogen production markets, are driving the diversification of carbon paper specifications and steady production growth. Simultaneously, the application of high-performance carbon paper in high-power-density fuel cells and long-life energy storage systems is driving technological iterations in thickness optimization, porosity control, and surface functionalization.

From a product roadmap and technology evolution perspective, the industry is undergoing multi-level material upgrades, including carbon fiber matrix optimization, refined resin impregnation and heat treatment, and exploration of surface functional coatings and composite functionalization. Regional supply chain migration, capacity expansion, and capital expenditure dynamics are impacting the global supply-demand balance and price system. In the future, the industry will continue to develop towards high performance, low cost, and long lifespan, but attention still needs to be paid to the potential localized substitution pressure from alternative materials (such as metal mesh diffusion layers or conductive composite films).
