Youveim® Platinum-Plated Titanium Mesh

(Expanded Diamond Mesh, Electroless Plating)
Stable Conductivity · Electrolyzer-Grade · A Reliable Alternative to Carbon GDLs

In water electrolysis for hydrogen production—particularly in PEM electrolyzers and other high-performance electrochemical systems—long-term material stability under high potential and oxygen-rich environments is a decisive factor for stack lifetime and operational reliability.

Youveim® Platinum-Plated Titanium Mesh (Expanded Diamond Mesh, Electroless Plating) is specifically engineered for these harsh conditions, combining research-grade precision with industrial-level durability.

Product Overview

Youveim® platinum-plated titanium mesh is manufactured from expanded titanium sheet, followed by flattening and annealing to obtain a mechanically stable and uniform diamond-shaped mesh structure.

A platinum layer is deposited via electroless plating, followed by vacuum thermal reduction or hydrogen thermal reduction, ensuring stable surface conductivity and long-term electrochemical reliability.

Primary Application

• Flow field / diffuser layer inside electrolyzer stacks

• Especially suited for the anode (oxygen evolution side)

• Designed to replace carbon-based gas diffusion layers (GDLs) commonly used in fuel cells

In certain designs, the material may also be used on the cathode side, and in limited fuel-cell architectures as well.

Why Carbon GDLs Fail on the Electrolyzer Anode

On the anode side (oxygen evolution reaction, OER) of an electrolyzer, materials are exposed to:

• High electrochemical potential

• Oxygen ions and reactive oxygen species

• Strongly oxidative environments

Under these conditions, carbon-based GDLs (carbon paper or carbon cloth) are thermodynamically unstable and undergo oxidation: C + O²⁻ → CO₂↑

Consequences:

• Rapid consumption of carbon material

• Loss of mechanical integrity and compression force

• Increased contact resistance

• Fast degradation of electrolyzer performance

📌 Conclusion:
Carbon-based GDLs are not suitable for the anode side, although they may still be used on the cathode (hydrogen evolution) side.

Why Bare Titanium Is Still Not Enough

Compared to carbon, titanium is not consumed under anodic conditions. However, in oxygen-rich, high-potential environments, titanium forms a passive TiO₂ layer.

TiO₂ is an excellent electrical insulator.

Result:

• Gradual increase in interfacial resistance

• Reduced current efficiency

• Performance decay during long-term operation

Although this degradation is slower than carbon oxidation, it becomes significant over extended operating periods.

The Role of Platinum-Plated Titanium Mesh

By depositing a platinum layer onto the titanium substrate, the following benefits are achieved:

• Suppression of TiO₂ passivation

• Stabilization of surface conductivity

• Improved electrochemical stability, especially on the anode

• Long-term maintenance of low and stable contact resistance

The structure is suitable for long-lifetime and pressurized electrolyzers, with pressure resistance of up to ~450 psi (≈31 bar), depending on design.

Platinum Coating Characteristics

• Platinum loading: 0.1–2.0 mg/cm² (based on physical surface area)

• Coating process: Electroless plating followed by

  • Vacuum thermal reduction, or

  • Hydrogen thermal reduction

Functional Purpose

• Enhance oxidation resistance

• Improve electrical stability under high anodic potential

• Ensure reliable long-term operation

⚠️ Important Note:
The platinum coating is not a continuous dense catalytic film.
Its function is conductivity and stability enhancement, not catalytic activity, and it is not intended to serve as an electrocatalyst.

Typical Applications

🔋 PEM water electrolyzer anode flow fields / diffuser layers
⚡ High-voltage, high-oxidation electrochemical systems
🧪 Research electrolyzers prioritizing stability and reproducibility
🏭 Industrial pressurized electrolyzer structural components

Summary

Youveim® Platinum-Plated Titanium Mesh (Expanded Diamond Mesh, Electroless Plating) is a functional material specifically developed for demanding electrolyzer environments:

• Long-term stable electrical conductivity

• Enhanced electrochemical stability, especially for anodes

• Oxidation-resistant and mechanically reliable structure

• Suitable for high-pressure and long-lifetime operation

It represents a proven and reliable alternative to carbon-based GDLs, providing robust support for next-generation, high-performance water electrolysis systems.
