Sigracet 39 BA is a non-woven carbon paper gas diffusion media. It has a total thickness of 190 um (microns). SGL BA is a great low-cost alternative to conventional woven carbon paper Gas Diffusion Layer (GDL) and Gas Diffusion Media materials.

The Sigracet Carbon Fiber Paper 39 Series is intended to combine the required production robustness and the excellent performance properties. Stack developers and assemblers are benefiting from the following greatly improved characteristics:

Greatly improved homogeneity inter-lot and intra-lot. The overall variability has been shown to be better than +/- 10% (2 sigma)
Greatly improved surface flatness
Greatly reduced occurrence of faulty spots on a roll
Best performance under various operating conditions
