Why Hydrogen Electrolysers Are Increasingly Using Platinum-Coated Titanium Mesh Anodes

by

The platinum-coated titanium mesh anode, a material choice that is quickly taking the lead in advanced water electrolysis systems, is one important factor influencing durability and efficiency.

Leading this change are businesses such as SAVEIONS LTD, which offer high-performance anode solutions with remarkable corrosion resistance, catalytic activity, and operational longevity.

1. Resistance to corrosion Designed for Extreme Electrolyser Conditions

Standard metals corrode rapidly in the extremely acidic environment used by hydrogen electrolysers, especially Proton Exchange Membrane (PEM) types.

Titanium Base: Because of its stable oxide layer, it is naturally resistant to corrosion.

Platinum Coating: Unmatched stability against oxidation and dissolution in acidic media is added by platinum coating.

By ensuring that the anode maintains its structure and conductivity over thousands of hours of operation, this combination lowers maintenance expenses and downtime.

2. Improved Performance of Oxygen Evolution Reaction (OER)


The slow oxygen evolution reaction (OER) must function effectively at the anode for water splitting to take place. Platinum is an excellent electrocatalyst:

  • Reduces OER’s overpotential.
  • Increases the efficiency of the current.
  • Increases the amount of hydrogen produced per unit of energy used.

Green hydrogen is now more affordable thanks to platinum-coated titanium mesh, which generates more hydrogen for every kilowatt of electricity.

3. Mesh Architecture for the Best Performance


There are two main benefits to a mesh structure:
High surface area: More reaction sites mean more catalytic activity, which is what high surface area means.
Better Gas Release: Oxygen bubbles escape more quickly, which reduces blockage and increases purity.
This design, along with the strength of titanium and the conductivity of platinum, allows for stable operation at high current densities.

4. Long-lasting on an Industrial Scale

To increase throughput, industrial electrolysers are moving towards current densities above 2 A/cm². Thanks to Platinum-coated titanium mesh can handle these loads without breaking down.

  • PVD or electroplating methods make platinum stick very well.
  • Little catalyst loss, even in harsh OER settings.

5. Works with more than one technology

Platinum-coated titanium mesh is used a lot in PEM electrolysis, but it can also be used for:

  • Alkaline Water Electrolysis (AWE)
  • Anion Exchange Membrane (AEM) Electrolysis
  • Chlor-alkali production Systems
  • Cathodic protection
    SAVEIONS also sells  MMO Titanium Mesh Anodes for other industrial electrochemical needs. These are a cheap option for some processes, like Hâ‚‚, Clâ‚‚, and COâ‚‚ electrolysis.

6. The cost of precious metals per unit is going down.

Thanks to new deposition technology, platinum layers are now very thin (<1 μm) and still work as catalysts. This cuts down on the amount of platinum used and the cost by a lot, all while keeping the same level of efficiency.

7. Advancing Green Hydrogen’s Future

Green hydrogen is getting closer to being as affordable as fossil fuels with each small increase in electrolyser efficiency. In addition to being a high-end enhancement, platinum-coated titanium mesh anodes are essential for:

  • Reduced electricity costs for each kilogramme of hydrogen.
  • longer periods of operation.
  • designs for small, high-output electrolysers.

These anodes are contributing to the development of the next generation of sustainable hydrogen production by fusing mechanical strength, chemical stability, and catalytic performance.
