The platinum-coated titanium plate electrode is the core electrolysis component of the alkaline water ion generator, composed of a high-purity titanium substrate and a micron-sized platinum coating. Titanium, as the structural support material, possesses excellent corrosion resistance, low density, and good conductivity, enabling it to withstand the strongly alkaline electrolysis environment stably for extended periods. Platinum, as the electrocatalytic active layer, significantly reduces the overpotential of water molecules in the oxygen evolution reaction (OER), improving electrolysis efficiency and reducing energy consumption. This structural design ensures the electrode remains stable even under continuous high current density, avoiding the corrosion and contamination problems of traditional graphite or lead-based electrodes, ensuring the generated alkaline water is pure and free of metal ion precipitation, meeting drinking water safety standards.

In practical applications, this type of electrode is widely used in household and commercial alkaline water ion generators. Its lifespan can reach 5 to 8 years, far exceeding that of traditional electrode materials, and it supports multi-stage electrolyzer operation in series, achieving wide pH adjustment. Its high catalytic activity not only promotes efficient hydrogen evolution at the cathode, increasing the dissolved hydrogen content in the water (antioxidant properties), but also effectively degrades organic pollutants in the water through synergistic electrochemical reactions, thus also possessing water purification functions. Currently, this technology has become the industry standard configuration for high-end water ion generators to ensure long-term stable operation of the equipment and the quality of the output water.
