A platinized titanium anode consists of a titanium substrate coated with a thin layer of platinum. Titanium, known for its high strength to weight ratio and excellent corrosion resistance, serves as an ideal base material. It can withstand the harsh environments of both acidic and alkaline electrolytes used in hydrogen production. The platinum coating, typically ranging from a few micrometers to tens of micrometers in thickness, is applied through methods such as electroplating or chemical vapor deposition. Platinum, a precious metal, is renowned for its outstanding electrocatalytic properties, making it highly effective in facilitating the electrochemical reactions necessary for hydrogen evolution.
Electrocatalytic Mechanism in Hydrogen Production
Alkaline Electrolysis:In alkaline electrolyzers (using KOH/NaOH electrolytes), the platinized titanium anode catalyzes water oxidation:2H2O→O2 +4H + +4e −
Platinum reduces the overpotential required for this reaction, minimizing energy loss and enhancing efficiency.
Proton-Exchange Membrane (PEM) Electrolysis:In acidic PEM systems, the anode reaction remains water oxidation:2H2O→O2 +4H + +4e −
Here, platinum’s high activity for the oxygen evolution reaction (OER) enables operation at high current densities (1–3 A/cm²), supporting compact, high-throughput hydrogen production.
Advantages of Platinized Titanium Anodes
High Catalytic Activity
Platinum’s unique d-band structure optimizes reaction kinetics, achieving near-ideal overpotentials (<20 mV at 10 mA/cm² in acidic media). This reduces cell voltage by 0.2–0.3V compared to non-precious metal anodes, translating to 10–15% energy savings in industrial systems.
Corrosion Resistance
Titanium’s passive oxide layer resists degradation in both acidic (PEM) and alkaline (AWE) electrolytes. A 2023 case study showed platinized titanium anodes maintained 95% activity after 8 years in a 30% KOH solution, outperforming nickel-plated steel by 200%.
Long Service Life
With proper maintenance (e.g., periodic citric acid flushing), these anodes can operate for 5–8 years. Plug Power’s alkaline electrolysis plants demonstrate <5% performance decay over 10,000 cycles, reducing replacement costs by 70%.
Application
Large-Scale Hydrogen Production
Chemical Industry: In ammonia synthesis, platinized titanium anodes in 10 MW AWE plants produce 99.9% pure hydrogen at 400 mA/cm², supporting 500 tons/day output.
Refining: PEM electrolyzers with Pt/Ti anodes supply high-purity hydrogen for hydrocracking, achieving 99.99% purity at 2.5 A/cm² (Norsk Hydro pilot data).
Renewable Energy Integration
SunHydrogen’s solar-driven PEM system pairs platinized titanium anodes with perovskite cells, achieving 18% energy conversion efficiency for off-grid hydrogen production.

production
1. Substrate treatment: it needs to be treated by roughing, cleaning and removing oil, which can increase the compactness of catalytic.
2. Brushing coating:After substrate treatment, it will be proceeded brush coated. The main coated content is platinum group metal, which is a kind of mixed solution.Then, heat treatment will be going on after drying.The whole procedure need to be repeated many times. This method is better to form thin oxide catalytic that is lamellar adhere to substrate surface.
