Platinum-coated porous titanium plates are essential components used in electrolyzers for diverse industrial applications such as hydrogen production, water treatment, and energy storage. These plates play a critical role in facilitating efficient and reliable electrochemical reactions.

Electrolyzers are devices that employ the principles of electrolysis to convert electrical energy into chemical energy or vice versa. They consist of anode and cathode compartments separated by an ion-conductive membrane or an electrolyte solution. The platinum-coated porous titanium plates serve as the electrodes within these compartments, facilitating the desired electrochemical reactions.

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.
