Fuel cell gas diffusion electrode porous tube
Fuel cell gas diffusion electrode porous tube
Advanced Porous Metal Tube Designed for Fuel Cell Gas Diffusion Electrode Systems
Our porous tubes for gas diffusion electrodes (GDE) are engineered for high-performance fuel cell systems, ensuring precise gas transport, optimized electrochemical reaction interfaces, and long-term durability under demanding operating conditions. These tubes combine porous metal sintering technology with customized structural design to meet the needs of PEMFC, SOFC, and alkaline fuel cells.
Key Advantages of Porous Tubes in GDE Systems
✅ Uniform Gas Distribution
Micro-porous structure enables even dispersion of hydrogen, oxygen, or air across the catalyst layer, ensuring consistent electrochemical reactions.
✅ High Electrical Conductivity
Made from sintered stainless steel, nickel, or titanium, our tubes support both gas flow and electron conduction within fuel cell stacks.
✅ Chemical and Thermal Resistance
Resists acidic/alkaline environments, oxidation, and high temperatures (up to 650°C) — ideal for PEMFC and SOFC systems.
✅ Custom Pore Size & Porosity
Tailor-made for pore size (1–20 µm), porosity (30–50%), and gas permeability to balance pressure drop, mass transport, and reaction kinetics.
✅ Structural Strength & Stability
Withstands internal gas pressure without deformation; suitable for integration into tubular fuel cells or reactor-type stacks.
