About this item

• GDL & Electrode Substrate: primarily used as a gas diffusion layer (GDL) for hydrogen and methanol fuel cells, and as an electrode substrate for supercapacitors and microbial fuel cells
• Hydrophilic Grade Option: available in two hydrophilic models: SL010N (0.1 mm thickness) and SL020N (0.19 mm thickness), with resistivity optimized for different cell designs
• High Porosity & Low Resistivity: high porosity (~75%) enables efficient gas and liquid transport, while low resistivity (2.5-5 mΩ·cm) ensures excellent in-plane electrical conductivity
• Standard Size & Mechanical Stability: supplied in a standard size of 20 x 20 cm, with a bending radius >5 cm and strong resistance to acids and alkalis for stable, reliable performance
• Ready-to-Use Surface Treatment: pre-treated hydrophilic surface allows direct use in material deposition, electrode fabrication, and fuel cell stack assembly without additional processing
• Custom Sizes Available: sheets can be customized to your required dimensions; please contact customer service for special size requests
