Spectracarb 2050A | Graphitized Carbon Fiber GDL Sheets
- Spectracarb 2050A - Multiple grades
- Gas Diffusion Layer Sheets
- Discontinued Q4 2020
Product Description
Spectracarb™ product line has been discontinued since 2020.
CAPLINQ has developed LINQCELL™ Carbon Fiber Paper GDL a better and more cost-effective alternative
Spectracarb™ 2050A Gas Diffusion Layer (GDL) sheets are sometimes called porous carbon gas diffusion layer. They are porous graphitized resin-bonded carbon fiber papers and multi-ply panels specifically designed for use in PEM, DMFC and PAFC fuel cells, Electrolyzers, Humidifiers and Other Electrochemical Devices.
Spectracarb 2050A Series Porous Graphitized Sheets and Panel
Spectracarb™ 2050A Porous Carbon Gas Diffusion Layer (GDL) sheets are porous graphitized resin-bonded carbon fiber papers and multi-ply panels specifically designed for use in PEM, DMFC and PAFC fuel cells, Electrolyzers, Humidifiers, and Other Electrochemical Devices
