Sigracet GDL 36 BB

Gas diffusion layers are used in fuel cells. Excellent electrical conductivity and effective water management provide superior fuel cell performance and durability in a wide variety of operating conditions.
 Sigracet 36 BB is a nonwoven carbon paper gas diffusion medium. It has a total thickness of 285 um (microns). SGL BB is a low cost alternative to traditional woven carbon paper Gas Diffusion Layer (GDL) and Gas Diffusion Media materials.
 Sigracet Carbon Fiber Paper 36 Series aims to combine the desired manufacturing rigidity and excellent performance characteristics. Fuel Cell Stack developers and installers benefit from the following greatly improved features:
 Greatly improved homogeneity within and within the batch. The overall variability has been shown to be better than +/- 10% (2 sigma)
 Highly improved surface smoothness
 Greatly reduced the occurrence of false spots on a roll
 Best performance in various operating conditions
