Sigracet 28 BC is a non-woven carbon paper featuring a Microporous Layer (MPL) with a 5 wt% PTFE treatment. With a total thickness of 235 µm, this hydrophobic treatment ensures water-repellent properties, preventing the flooding of highly porous carbon fiber backings. It actively supports the efficient water management essential for PEM fuel cells. SGL 28 BC offers a cost-effective alternative to traditional woven carbon paper Gas Diffusion Layer (GDL) materials.
The Sigracet Carbon Fiber Paper 28 Series is designed to deliver exceptional production robustness alongside outstanding performance characteristics. 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
- Recommended Applications: PEMFC stationary, PEMFC automotive
Standard dimensions: 10 cm x 10 cm. For other dimension please ask for a quote.
