Titanium Anode for Water Electrolyzer

Titanium Anode for Water Electrolyzer

In water electrolyzers, the anode is the core component that determines electrolysis efficiency, output water quality, and equipment service life. Our Titanium Anode for Water Electrolyzer at Baoji City ShenAo Metal Materials Co., Ltd. is designed specifically for continuous or intermittent electrolysis in household and commercial alkaline ion water machines and functional water generation equipment. It uses Grade 1 or Grade 2 pure titanium as the substrate, with a noble metal oxide catalytic coating on the surface. The coating maintains stable oxygen evolution catalytic activity in low-concentration electrolyte water, operating reliably in diaphragm-type electrolysis environments. The anode maintains a stable chemical state during operation, minimizing the risk of metal ion dissolution and preventing secondary contamination of the product water, making it suitable for various water electrolysis equipment producing alkaline drinking ion water, acidic beauty water, and electrolytic functional water, serving as a reliable electrode solution for ensuring output water quality and long-cycle stable equipment operation.

This product is for B2B industrial and commercial equipment use only. Operators should follow relevant chemical safety protocols and electrical operation standards.

Technical Specifications

Why Choose Our Titanium Anodes?

• Stable Electrolytic Activity and Output Water Quality
  The coating maintains low oxygen evolution overpotential even in low-conductivity water, ensuring efficient and stable electrolysis. Over long-term operation, the coating consumption rate is very low, with minimal metal ion dissolution, safeguarding the cleanliness of the product water at its source. For equipment requiring consistent output of functional water with stable pH and oxidation-reduction potential, this stability forms the foundation for process consistency.
• Adaptability to Low-Concentration Electrolysis Conditions
  Water electrolyzers typically use tap water without additional salt dosing or with only trace electrolyte addition, resulting in conductivity far lower than industrial electrolytes. Our coating formulation is optimized for such lean electrolyte conditions, maintaining good electrochemical reaction efficiency at limited ion concentrations and avoiding cell voltage rise caused by concentration polarization.
• Clean and Safe Material System
  The coating employs a noble metal oxide system validated through long-term use, remaining chemically stable within the normal electrolysis potential window. The titanium substrate offers excellent resistance to aqueous corrosion. The entire electrode introduces no heavy metals or other harmful leachables during use, making it suitable for applications involving food contact and high hygiene requirements.
• Compatibility with Various Equipment Structures
  We can supply anodes in flat plate, perforated mesh, woven mesh, and other configurations, compatible with mainstream continuous-flow electrolysis cells and batch-type ion water generator designs. Whether your equipment uses a vertical filter-press layout or a horizontal multi-cell series configuration, electrode solutions with matching dimensions and connections are available.

Real-World Applications

• Household Appliance Manufacturing: Used as anode assemblies in household alkaline ion water machines, benchtop electrolytic water pitchers, and under-sink electrolytic water devices, covering electrolytic water generation equipment for daily drinking, cooking, and tea brewing applications.
• Commercial Water Purification and Dispensing Equipment: Used in electrolysis modules for commercial water purification terminals, office water dispensers, and hotel and catering water treatment equipment, covering combined supply solutions for ambient drinking water and electrolytic functional water.
• Functional Water Equipment Manufacturing: Used as anode assemblies in equipment generating acidic beauty water, cleaning and disinfecting water, and agricultural irrigation functional water, covering electrolytic functional water preparation for beauty salons, food processing, and household cleaning applications.
• Water Electrolyzer OEM Supply: Used as anode assembly supply for manufacturers of water electrolyzers, ion water generators, and functional water generation equipment, covering standard anodes and custom-designed anodes per design specifications.

The ShenAo Advantage

18 Years of Fabricating Excellence

Since 2008, we've specialized in valuable metal coated titanium anodes from our office in Baoji's "China Titanium Valley." Our develop bimetallic hazardous welding innovation and progressed coating forms provide items you can trust.

Customization for Your Correct Needs

Every generation line is diverse. We give custom fitted arrangements coordinating your particular current thickness necessities, electrolyte composition, and operational parameters. Whether you require little bunch testing or full-scale generation amounts, we convey on time.

Cost-Effective Lifecycle Management

When coating exhaustion happens, you do not dispose of the whole anode. Our proficient recoating benefit strips the ancient oxide layer, sandblasts the substrate, and reapplies new MMO coating. This expands resource life and decreases your add up to taken a toll of proprietorship considerably.

Frequently Asked Questions

Q: What type of coating is typically used for titanium anodes in water electrolyzers?
A: It depends on the type of water the equipment produces. For equipment primarily producing alkaline drinking water, iridium-based coatings with good oxygen evolution activity are typically used on the anode side, maintaining stability under tap water electrolysis conditions. For equipment that also produces acidic functional water, iridium-ruthenium coatings can be selected, utilizing their oxygen evolution activity to maintain stable electrolysis efficiency on the anode side. We recommend providing your equipment design parameters and water quality report for evaluation.

Q: What factors most significantly affect anode service life?
A: Key factors include: feed water hardness (calcium and magnesium ion content), electrolysis intensity, operating duration, and electrode polarity reversal frequency. Water with higher hardness tends to form scale on the anode surface, increasing cell voltage. It is recommended to install softening and pretreatment units before the water inlet. Regular electrode polarity reversal or acid cleaning maintenance can also help extend service life.

Q: Is it normal for the anode surface to turn yellow or discolored after long-term use?
A: The titanium substrate naturally forms a very thin oxide film in the water electrolysis environment, appearing pale yellow or light brown. This is a normal passivation phenomenon of titanium and does not affect the electrode's conductivity or catalytic activity. However, if the color darkens significantly to deep brown or patchy flaking appears, an inspection is recommended.

Q: How are finished anodes packaged and shipped?
A: Each anode is individually wrapped in protective packaging to prevent scratching of the coating surface during transit. Bulk orders use custom foam lining boards and sturdy outer cartons to ensure shock and moisture protection during transportation. Export orders can be provided with fumigated wooden crates or air freight-specific packaging upon request.​​​​​​​
