SSI-GH is the first in China to use a roll-to-roll process to produce gas diffusion layers. At present, the maximum width of the product can reach 1.2m, which is more suitable for automatic production.The product has stronger electronic conductivity, stronger water management ability, excellent air permeability, high mechanical strength, appropriate rigidity and flexibility, excellent chemical stability and thermal stability under the advantages of ultra-thin,structural Tight and surface balanced for high durability. We have realized the full-process manufacturing and online process quality control from base paper-carbon paper-gas diffusion layer,and at the same time have better product consistency, and some product performance indicators have reached the international advanced level. At present, we have launched gas diffusion layer products suitable for air-cooled hydrogen fuel cells, liquid-cooled hydrogen fuel cells and cathodes of PEM water electrolysis hydrogen production electrolyzers.
