Carbon Cloth: Roll type
W series is a unique design for carbon cloth GDL. The 2nd generation of carbon substrate in woven type is developed to be highly suitable for the MEA process. Currently, we have two different carbon cloths in the new generation, in which they are typically varied in thickness. This series product items can all be furthermore adjusted the hydrophobicity level to ensure the best fuel cell efficiency. Please be informed that advantages of W Series include its high strength and even pore size; besides, the two proprieties can also be reinforced by MPL coating. Please find the sheet below for CeTech current products of W series. For more details or help, you are surely welcome to contact us. |
