Carbon Paper
We have fully internalized our GDL production by in-housing the water repellent coating & microporous layer (MPL) coating process
Carbon paper is also called the gas diffusion backing layer (GDBL), which is a backing layer of a non-woven structure created through a wet-laid process using carbon fiber. The GDBL used in PEMFCs needs to have uniform thickness, low electrical resistance, and high mechanical strength.
We optimized the composition and structure of our GDBL so that our GDL can have a superior structure. The R&D goal of JNTG was to create a product with uniform thickness and porosity that can improve the performance of the membrane electrode assembly (MEA) in a fuel cell.
