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.
