HCP331P Hard Carbon Cloth - Rigid Hydrophobic Gas Diffusion Layer

Description

The HCP331P is engineered for applications where mechanical durability and water management must coexist. Its rigid woven structure ensures that the thickness remains uniform even under significant clamping force in a battery stack. The integrated PTFE treatment provides a robust hydrophobic barrier, effectively expelling liquid water while allowing reactant gases to reach the catalyst layer. If your research involves high-pressure cell assembly or long-term durability testing, the HCP331P is the professional-grade choice.

Features

• High Rigidity: Specially processed to be stiffer than the 330 series, preventing "sink-in" effects under stack compression.
• Superior Water Repellency: High-load PTFE treatment ensures long-lasting hydrophobicity and prevents GDL flooding.
• Structural Stability: Maintains its porous network and gas permeability under high mechanical stress.
• Excellent Conductivity: High carbon density ensures low contact resistance and efficient electron transport.
• Precision Surface: Offers a flatter, more consistent surface for uniform catalyst ink application.
