Product Overview



In combination with Ballard Power Systems' leadership and expertise in the development and manufacturing of proton exchange membrane (PEM) fuel cells, Ballard Material Products (BMP) introduces its AvCarb Grade-P75 carbon fiber paper. Specifically developed for gas diffusion layer (GDL) applications in PEM fuel cells and other applications requiring a conductive substrate, AvCarb P75 is a carbon particle-filled, polyacrylonitrile (PAN) based carbon fiber paper manufactured utilizing BMP's exclusive AccuCarb continuous carbonization process. Under development for over two years, Ballard's AvCarb P75 has the potential for becoming the lowest cost GDL available, thus providing a stimulus for the growth of fuel cell applications.

AvCarb P75 is the result of Ballard identifying key electrical, mechanical and gas/liquid diffusion properties needed by GDL users and designing a product to meet those requirements. AvCarb P75 is a baseline product that can be design modified to optimize specific performance characteristics. The paper can also be supplied with hydrophobic coating that minimizes the effects of moisture exposure, enhances performance, provides durability and facilitates handling. When supplied with the hydrophobic coating the Grade designation becomes AvCarb P75T.
