Platinum Coated Porous Titanium Sheets Electrodes For PEM Water Electrolyzer

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.

The platinum-coated porous titanium electrode sheets are highly effective electrode materials in acidic environments. These products find applications in organic electrolysis, such as cysteine, Cr3+, Cr6+, CN, and toxic substance electrolysis. They can also serve as auxiliary electrodes in the electroplating industry, including as auxiliary anodes for chromium, electrolytic copper, and electrolytic zinc, as well as in electrolytic cobalt and nickel processes.
