Porous titanium sheets are highly desirable for use as the porous transport layer (PTL) in polymer electrolyte membrane (PEM) water electrolyzers. However, the passivation of titanium leads to an increase in surface contact resistance, thereby negatively affecting the performance of the electrolyzer. To address this issue and ensure long-term operation, a common approach is to apply platinum or gold coatings on titanium-based PTLs. Parameters Material: Sintered Porous Titanium Sheet Coating: Platinum (Pt) The thickness of platinum: 1 micron Porosity: Customizable, commonly between 30% and 40% Pore Size: 10 microns Size: 46*46* 2mm Features Enhanced Conductivity: The platinum coating on sintered porous titanium sheets provides excellent electrical conductivity, facilitating efficient electron transfer during electrochemical reactions. Durability and Corrosion Resistance: Titanium's inherent corrosion resistance, combined with the protective platinum coating, ensures prolonged electrode lifespan, even in aggressive chemical environments. High Surface Area: The porous structure of the titanium sheets offers a large surface area, enabling more active sites for electrochemical reactions and enhancing cell efficiency. Customizable Pore Size: The pore size of sintered porous titanium sheets can be tailored to specific applications, allowing for optimized mass transport and improved electrolyte flow.

TOPTITECH has developed the thinnest porous titanium plate on the market for use as an anode diffusion layer in standard PEM electrolysers. Metallic or titanium-based electrodes serve as the flow field or diffusion material in standard PEM electrolyzers, particularly on the oxygen (anode) side, to ensure improved mass transport and a compact design. The use of carbon-based gas diffusion layers (GDLs) is not viable at the anode due to immediate carbon oxidation to CO2 (under acidic conditions) or carbonate ions (under basic conditions). To address this limitation, the titanium porous transfer layer emerges as an optimal choice for the diffusion medium. Additionally, the titanium porous transfer layer facilitates electrical connectivity between the anode catalyst layer and the bipolar plate or current collector component.
