Product Overview
GDS-2120 is based on BMP¬AvCarb P75 carbon fiber paper substrate, which is treated to render it hydrophobic, and then coated with a micro-porous layer for the control of permeability, diffusivity and conductivity at the catalyst interface. The team approach to development of the GDS identified key electrical, mechanical and gas/liquid diffusion properties needed to meet PEM fuel cell requirements. GDS- 2120 can be modified for alternate levels of hydrophobic treatment in both the substrate and the micro-porous layer, enabling further design flexibility for water management and gas transport characteristics. The new GDS offers advantages of continuous roll processing, improved thickness and areal weight uniformity and ease of storage and compatibility with subsequent continuous manufacturing processes. Further, Ballard¬ AvCarbGDS has the potential for becoming the lowest cost GDL available, thus providing a stimulus for the growth of fuel cell applications. Details
