AvCarb P75T
Fuel Cell / Electrochemical Research Material
제품 안내
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-P75T carbon fiber paper. Specifically developed for gas diffusion layer (GDL) applications in PEM fuel cells and other applications requiring a conductive substrate, AvCarb P75T 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 P75T has the potential for becoming the lowest cost GDL available, thus providing a stimulus for the growth of fuel cell applications. AvCarb P75T is the result of Ballard identifying key electrical, mechanical and gas/liquid diffusion properties needed by GDL users and designing a product to...
