Sintered titanium felt, fabricated via high-temperature sintering of titanium fibers, offers a porous structure with exceptional permeability, corrosion resistance, and thermal stability. Its interconnected 3D network ensures uniform fluid/gas distribution, high mechanical strength (>15 MPa), and customizable porosity (60-85%). Ideal for PEM electrolyzers, fuel cells, and catalytic reactors, Tested in aggressive media (pH 1-14) and elevated temperatures (<400°C), it demonstrates durability (>8,000 hours) and low contact resistance. Lightweight and scalable, sintered titanium felt enhances performance in energy conversion, filtration, and chemical processing, serving as a robust solution for harsh-environment applications.
