Working Principle of Titanium Anodes in Hydrogen Production

In industrial hydrogen production systems, water is decomposed into hydrogen and oxygen through an electrochemical reaction.

The titanium anode acts as the oxygen evolution electrode. The reaction process is as follows:

Cathode

Hydrogen gas generation:

2H₂O + 2e⁻→ H₂ + 2OH⁻

Anode

Oxygen evolution reaction:

4OH⁻→ O₂ + 2H₂O + 4e⁻

The MMO catalytic coating on the titanium anode reduces the oxygen evolution overpotential, improves conductivity, and enhances the efficiency of the electrochemical reaction.
