High-Performance Titanium Anodes for Efficient Hydrogen Production

Baoji Shenao Metal Materials Co., Ltd. is a professional manufacturer of titanium anodes for electrolytic hydrogen production, specializing in MMO-coated titanium anodes, ruthenium-iridium-coated titanium electrodes, and customized electrolytic anode solutions for hydrogen production systems. We provide industrial-grade titanium anodes with high conductivity, low energy consumption, long service life, and stable electrochemical performance.

Whether for alkaline electrolyzers, PEM hydrogen production systems, seawater electrolysis equipment, or industrial hydrogen production plants, our titanium anodes offer reliable performance and lower operating costs.

Titanium anodes for electrolytic hydrogen production are electrochemical electrodes used in water electrolysis systems to produce hydrogen. The titanium substrate is coated with a catalytic noble metal oxide, such as ruthenium, iridium, platinum, or mixed metal oxides (MMO).

During electrolysis:

Water decomposes into hydrogen and oxygen.

Hydrogen is produced at the cathode.

The titanium anode promotes the oxygen evolution reaction (OER).

The coating improves catalytic efficiency and corrosion resistance.

Compared to traditional graphite or lead electrodes, titanium anodes offer:

Higher conductivity

Better corrosion resistance

Longer service life

Lower energy consumption

Stable electrochemical activity

Titanium anodes for hydrogen electrolysis have become the ideal choice for the modern hydrogen energy industry.

Working Principle of Titanium Anodes in Hydrogen Electrolysis

Electrochemical Reaction Process

In hydrogen electrolysis systems, electricity is applied to water or electrolyte solutions.

At the Cathode

Hydrogen ions gain electrons and form hydrogen gas:

2H++2e−→H22H^+ + 2e^- → H_22H++2e−→H2​

At the Titanium Anode

Water molecules lose electrons and generate oxygen:

2H2O→O2+4H++4e−2H_2O → O_2 + 4H^+ + 4e^-2H2​O→O2​+4H++4e−

The titanium anode coating acts as an electrocatalyst to accelerate oxygen evolution while maintaining stable operation under harsh electrochemical conditions.
