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
