Product Overview
This high-conductivity carbon cloth is a premium woven carbon fiber substrate engineered specifically for demanding electrochemical architectures and advanced energy storage systems. Designed to serve as a high-efficiency gas diffusion layer (GDL) and current collector substrate, the material features an open woven textile structure combined with superior electrical and thermal transport properties. By maintaining minimal bulk and contact resistance, it facilitates rapid charge transfer across the electrode interface while enabling uninhibited mass transport of reactant gases and liquid electrolytes.
Optimized for cutting-edge energy technology sectors, this material is extensively utilized in proton exchange membrane fuel cells (PEMFC), direct methanol fuel cells (DMFC), redox flow batteries (RFB), and high-rate electrochemical supercapacitors. Its high surface integrity and continuous fiber construction also make it a reliable choice for electrocatalysis research, environmental remediation electrodes, and customized battery prototyping where structural resilience and electrochemical stability under corrosive conditions are mandatory.
Manufactured under rigorous quality control standards, the woven substrate demonstrates exceptional mechanical endurance and batch-to-batch consistency. It withstands continuous mechanical compression within cell stacks without fiber breakage or pinhole formation, ensuring prolonged operational life and stable power densities even during high-current cycling, wide temperature fluctuations, and aggressive chemical environments.
Key Features
- Ultra-Low Through-Plane Electrical Resistance: Exhibiting a through-plane resistance of less than 5 mΩ·cm² under standard ASTM C-611 test conditions, this substrate ensures rapid electron transfer across the electrode interface, significantly reducing internal ohmic losses and maximizing cell operating voltage.
- Optimized Macroporous Air Permeability: With a Gurley air permeability rating of less than 10 seconds, the woven pore network facilitates efficient fluid and gas dynamics, preventing localized mass-transport overpotential and flooding during high-current-density fuel cell operations.
- Controlled Micro-Uniform Thickness: Precision-calibrated to 0.33 ± 0.03 mm via standard TECLOCK SM-114 measurement protocols, the cloth delivers uniform stack compression, stable thermal dissipation, and consistent sealing across multi-cell bipolar plate assemblies.
- Engineered Anisotropic Tensile Strength: Providing a machine direction (MD) tensile strength of 10 N/cm (ASTM D-828) and a cross direction (XD) strength of 5 N/cm, the cloth resists tearing and distortion during automated roll-to-roll coating, catalyst slurry deposition, and high-pressure cell stack assembly.
- Balanced Areal Weight: Calibrated to 120 g/m² under ASTM D-646 standards, the material provides an optimal balance between structural rigidity and active volumetric energy density, minimizing overall stack weight without compromising mechanical integrity.
- Superior Chemical and Electrochemical Corrosion Resistance: Constructed from high-purity graphitic woven fibers, the material exhibits outstanding chemical inertness against acidic electrolytes, aggressive oxidizers, and broad potential windows encountered in continuous electrochemical cycling.
- Excellent Catalyst Slurry Receptivity: The textured woven fiber matrix enables uniform adhesion and deep penetration of electrocatalyst inks, minimizing catalyst delamination during prolonged hydrothermal operations.
