What are the advantages of ruthenium-iridium coated porous titanium plate compared to ruthenium-iridium coated titanium plate?

Enhanced Mass Transfer Efficiency

Traditional Ru - Ir coated titanium plates have served the industry well, but they often face limitations in mass transfer. In contrast, our porous titanium plate is a breakthrough. The porous structure creates a vast network of channels, increasing the surface area available for reactant and product exchange. This means that in applications such as PEM electrolyzers, gases like oxygen and hydrogen can be transported to and from the reaction sites much faster. For example, in a PEM electrolyzer, the porous design allows water molecules to reach the catalyst layer more efficiently, resulting in a significant boost in the rate of oxygen evolution reaction.

Superior Catalytic Activity

The Ru - Ir coating on both traditional and our porous plates is known for its catalytic prowess. However, the porous nature of our plate takes this a step further. The increased surface area provided by the pores allows for a more uniform distribution of the Ru - Ir catalyst. This means that more active sites are exposed to the reactants, maximizing the catalytic effect. In fuel cell applications, this results in a higher power density. This is a remarkable improvement, translating into more powerful and efficient fuel cell systems.

applications

1. Proton Exchange Membrane (PEM) Electrolyzers

In PEM electrolyzers, our Ru - Ir coated porous titanium plate serves as a vital component. It functions as the anode diffusion layer, facilitating the transport of water to the catalyst layer for electrolysis. The large surface area provided by the porous structure allows for efficient oxidation of water molecules, generating oxygen gas, protons, and electrons. The Ru - Ir coating's high catalytic activity reduces the overpotential required for the reaction, increasing the overall energy efficiency of the electrolyzer.

2. Fuel Cells

For fuel cells, this product plays a crucial role as a gas diffusion layer. It enables the uniform distribution of fuel gases (such as hydrogen) and oxidants (such as oxygen) to the catalyst layers. The porous structure ensures that the reactant gases can reach the catalyst sites rapidly, while also allowing the efficient removal of reaction by - products, such as water vapor. The Ru - Ir coating enhances the electrochemical reactions at the catalyst layer, improving the power output and performance of the fuel cell.

3. Chlor - Alkali Industry

In the chlor - alkali process, where brine is electrolyzed to produce chlorine, sodium hydroxide, and hydrogen, our Ru - Ir coated porous titanium plate can be used as an anode. The corrosion - resistant nature of the plate, combined with the catalytic activity of the Ru - Ir coating, allows for efficient and stable operation in the highly corrosive brine environment. This leads to increased productivity and reduced maintenance costs.
