Sigracet 39 AA
Fuel Cell / Electrochemical Research Material
제품 안내
Sigracet 39 AA is a non-woven carbon paper gas diffusion media that has no PTFE treatment. It has a total thickness of 280 um (microns). SGL AA 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 Sigracet 39AA is the successor type to Sigracet 35AA. The thickness, areal weight and in-plane permeability (IPP) of...
