Working Principle of Titanium Anodes in Hydrogen Electrolysis
In water electrolysis, the titanium anode serves as the oxygen evolution electrode (OER). The MMO mixed metal oxide catalytic coating reduces the OER overpotential, improves current efficiency, and ensures stable, continuous hydrogen production.
In industrial electrolysis systems, the titanium substrate provides corrosion resistance and mechanical strength, while the noble metal oxide coating accelerates the electrochemical reaction and enhances long-term corrosion resistance.
Our titanium anodes for hydrogen electrolysis are widely used in:
PEM proton exchange membrane electrolyzers
Alkaline water electrolysis systems
Renewable energy hydrogen production projects
Seawater electrolysis equipment
Industrial hydrogen generators
Electrochemical hydrogen production systems
