Fuel Cell / Electrochemical Research Material
제품 안내
This product has been discontinued and we are completely out of stock. Sigracet 29 BC was discontinued and permanently replaced by Sigracet 22 BB. Sigracet 29 BC is a non-woven carbon paper with a Microporous Layer (MPL) that has been PTFE treated to 5 wt%. It has a total thickness of 235 um (microns). SGL 29 BC is a great low-cost alternative to conventional woven carbon paper Gas Diffusion Layer (GDL) materials. The Sigracet Carbon Fiber Paper 29 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...
