Technical Parameters of Titanium Anode for Alkaline Water Electrolysis

These parameters can be customized based on the customer’s specific electrolysis system requirements.

Key Advantages of Titanium anode for alkaline water electrolysis:

1. Superior Corrosion Resistance
   Titanium’s inherent resistance to corrosion ensures durability, even in highly alkaline environments.
2. High Electrical Efficiency
   Coated with noble metals like ruthenium and iridium, the anode minimizes energy loss and enhances operational efficiency.
3. Tailored Design
   Available in custom sizes and configurations to suit diverse industrial applications.
4. Environmental Sustainability
   Enables clean hydrogen production, aligning with energy-saving and eco-friendly initiatives.
5. Cost-Effective
   Long service life reduces maintenance costs and operational downtime.

Applications of Titanium Anodes in Alkaline Water Electrolysis
1. Hydrogen Production

The most important application is in green hydrogen production, where renewable energy sources (solar, wind, or hydro) power the electrolysis process. Titanium anodes ensure high-efficiency oxygen generation and minimal energy loss, directly influencing the hydrogen output rate.

2. Chlor-Alkali Industry

In addition to hydrogen production, titanium anodes are widely used in chlor-alkali cells for producing chlorine (Cl₂), sodium hydroxide (NaOH), and hydrogen (H₂). Their stability and resistance to chloride corrosion make them ideal for these harsh environments.

3. Water Treatment and Electrochemical Oxidation

Titanium anodes are also employed in electrochemical oxidation processes for wastewater treatment, including the removal of organic pollutants and ammonia. Their ability to generate active oxygen species makes them efficient in degrading persistent contaminants.​​​​​​​

4. Energy Storage and Fuel Cells

Advanced research has also explored titanium-based electrodes in reversible fuel cells and metal-air batteries. Their chemical stability and conductivity make them a promising component in next-generation energy systems.

Titanium anode for alkaline water electrolysis Case: 
1: 5 MW Alkaline Hydrogen Plant

In a 5 MW hydrogen production project, titanium anodes with IrO₂–Ta₂O₅ coatings were deployed. The system achieved:

Current density: 0.5 A/cm²

Cell voltage: <1.9 V

Operating life: over 30,000 hours
The result was a 15% energy efficiency improvement and a significant reduction in maintenance costs.

2: Wastewater Electrolysis System

A municipal wastewater treatment facility implemented titanium anodes for electrochemical oxidation of COD. The electrodes maintained stable performance for over 24 months with negligible coating degradation, proving their robustness in real-world alkaline environments.
