N series of CeTech is a porous carbon paper that adapts PAN-based carbon-fiber with high gas-permeability and conductivity. The 2^nd generation of carbon substrate has very even pore size in carbon structure, and to reorganize this character, please look into the properties “bubble point” and “pore size” shown in the sheet below. The other feature we emphasize is “Tensile Property” showing the mechanical strength, which is also what users may have lots of concern when assembling. Our paper material is suitable for all the full cell configurations. Please find the sheet below for CeTech current products of N series. For the details or any help, you are welcome to contact us.
