0.1Mm Ultra-Thin Titanium Porous Transfer Layer

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.
