Spectracarb
2050A Porous Carbon-Carbon Paper
OVERVIEW:
Spectracarb™ 2050A porous carbon-carbon papers, developed
by Spectracorp and now produced by Engineered Fibers Technology,
are available for use in demanding applications such as PEM fuel
cell gas diffusion layer (GDL) electrodes. As shown in the photomicrograph,
Spectracarb paper consists of a graphitized network of resin-bonded
carbon fiber. This offers good air/water permeability, while also
providing structural rigidity and high electrical conductivity.
The Spectracarb 2050A series is available in a wide range of standard
grades, and EFT has the capability of producing custom grades from
pilot-scale to full commercial production in order to meet customer-specific
targets.
FEATURES:
• High electrical conductivity, resulting from high temperature
graphitization process
• High strength and durability
• Good air permeability and moisture transport
• Laboratory support is available to help prototype new customer
applications
• Domestically produced
