Market Size

The Porous Transport Layer (PTL) market refers to the industry involved in the manufacturing, development, and distribution of porous materials that are primarily used in proton exchange membrane (PEM) fuel cells and electrolyzers. These layers play a crucial role in the performance of electrochemical devices by facilitating efficient transport of gases, water, and heat. PTLs are typically composed of sintered metals, carbon-based materials, or metal foams and serve as a critical interface between the catalyst layer and flow field. Their porous structure allows for optimal diffusion of reactants, removal of by-products, and effective current collection.

In recent years, the demand for PTLs has surged due to the growing emphasis on clean energy solutions, particularly in automotive fuel cells, industrial hydrogen generation, and portable energy systems. With the global shift toward decarbonization and sustainable technologies, PTLs are increasingly being adopted in energy storage and conversion systems, including PEM fuel cells, electrolyzers, and redox flow batteries.
