Product Introduction

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.

Its uniform material transfer capabilities enable precise and controlled deposition of bioactive substances and enhance the performance of biomedical devices.

When is it appropriate to utilize a Platinized Titanium Porous Transfer Layer?

Unlike a carbon Gas Diffusion Layer (GDL), an untreated titanium porous transfer layer does not undergo consumption. However, the presence of oxygen can have an impact when operating the electrolyzer at high pressures ranging from 1 bar to 3 bars. Under these conditions, the untreated titanium surface rapidly forms an electrically insulating oxide layer (TiO2) on the small-diameter fiber surface. This oxide coating ultimately hampers the system's efficiency by acting as an electrical insulator and increasing interfacial resistance within the cell, leading to decreased electrochemical performance.

To prevent the formation of this oxide coating, the application of a gold or platinum coating is recommended. Platinizing the titanium surface results in a conductive and chemically stable coating, ensuring the longevity of the titanium material. This platinized layer is particularly beneficial for applications that require high performance and prolonged operational life. By inhibiting the development of TiO2, the electrochemical performance of the electrolyzer or intended electrochemical device can be greatly improved.
