4x8mm Diamond Micro Hole Expanded Metal Titanium Mesh for Fuel Cell Anodes

Description of Expanded Metal Mesh

The 4x8mm Diamond Micro Hole Expanded Metal Titanium Mesh is a high-performance engineering material specifically developed for advanced Electrochemical and Fuel Cell applications. Manufactured from premium Grade 1 or Grade 2 Titanium, this mesh features a precision-expanded diamond structure that is subsequentely flattened to ensure a perfectly smooth surface.

The 4x8mm aperture is an optimized "Micro Hole" configuration that balances structural integrity with maximum open area. This geometry is critical for ensuring uniform gas diffusion and consistent electrical contact across the electrode surface. With its exceptional strength-to-weight ratio and innate resistance to extreme chemical environments, this titanium mesh serves as a superior substrate for high-efficiency catalytic coatings.

Specification of Expanded Metal Mesh

Features of Expanded Metal Mesh

Titanium is a lightweight yet high-strength metal with excellent corrosion resistance and chemical stability. In the process of hydrogen production via water electrolysis, electrode materials need to be exposed to acidic or alkaline electrolytes for long periods, and titanium mesh can effectively resist corrosion and extend the service life of equipment. Titanium mesh boasts good electrical conductivity, and its surface can be treated with special processes to form an active coating, which further improves electrolysis efficiency. Manufacturing enterprises in Hebei Province leverage local resource advantages and produce high-quality titanium mesh products through precision processing technologies, meeting the hydrogen production needs of different scales.

Applications of of Expanded Metal Mesh

1. Fuel Cell Anode & GDL Support

In Proton Exchange Membrane (PEM) Fuel Cells, this mesh serves as a critical component in the membrane electrode assembly (MEA).

Gas Diffusion Support: The 4x8mm diamond pattern allows for the efficient transport of hydrogen gas while providing mechanical support to the delicate catalyst layer.

Current Collection: The continuous, jointless structure of the expanded metal ensures low electrical resistance and efficient electron flow.

2. Advanced Electrolyzers (Hydrogen Production)

Designed to withstand the harsh oxidative environments found in water electrolysis systems.

Oxygen Evolution Reaction (OER): Acts as a stable anode substrate that can be coated with precious metals (Platinum, Iridium) to facilitate high-purity hydrogen production.

Bubble Management: The micro-hole geometry promotes the rapid detachment of gas bubbles, preventing "shielding" effects and maintaining high cell efficiency.

3. High-Precision Filtration

The flattened, smooth surface makes it ideal for liquid and gas filtration in high-purity industries.

Chemical Processing: Used for filtering aggressive acids and alkalis that would degrade stainless steel or polymer filters.

Aerospace & Defense: Utilized in lightweight, corrosion-resistant components for hydraulic systems and environmental control units.

4. Electrochemical Water Treatment

The large surface area provided by the diamond mesh design enhances the efficiency of electrochemical reactions.

Advanced Oxidation Processes (AOP): Used as an electrode for the degradation of persistent organic pollutants.

Ion Exchange Systems: Provides a stable conductive path in electro-deionization (EDI) modules.
