Sigracet Gas Diffusion Layer Carbon Paper, 3 sheets

Description

The newly improved Sigracet carbon fiber paper series gas diffusion layers are intended to combine the required production robustness and the excellent performance properties in which stack developers and assemblers are benefiting from:

• 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
