  • Product Description

    Gas Diffusion Layer
    Our GDL is the first domestic mass production product of gas diffusion layer that adopts the roll-to-roll production process. We have launched three series of standard products and provide customized services for liquid-cooled fuel cells, air-cooled fuel cells and hydroelectrolysis cells.Our coil width can be up to 1.2 meters to meet more needs. Annual production capacity of 1.1 million square meters.


    Gas Diffusion Layer Features
    Strong conductivity
    Strong water management ability
    Excellent air permeability
    High mechanical strength
    Long durability
    Smooth Surface


    After more than three years of market validation, our gasdiffusion layer liquid cooling series products have high suitability and excellent battery performance in fuel cells.
