Application

Hydrogen Production: Platinum-coated porous titanium plates are extensively used in electrolyzers for hydrogen production through water electrolysis. The plates serve as both the anode and cathode, enabling the splitting of water molecules into hydrogen and oxygen. The high catalytic activity of platinum promotes faster reactions, while the porous titanium structure allows for efficient gas diffusion, ensuring optimal performance.

Water Treatment: Electrochemical water treatment methods, such as electrocoagulation and electrooxidation, employ platinum-coated porous titanium plates as electrodes. These plates aid in the removal of pollutants, heavy metals, and organic compounds from wastewater. The porous structure enhances mass transfer and increases the electroactive surface area, facilitating effective treatment processes.

Energy Storage: Platinum-coated porous titanium plates find application in regenerative fuel cells and electrolyzers for energy storage. During periods of excess renewable energy generation, the electrolyzers utilize surplus electricity to produce hydrogen through electrolysis. The produced hydrogen can later be used in fuel cells to generate electricity when the demand exceeds supply, allowing for efficient energy storage and utilization.
