Titanium (Ti) felt—often called sintered titanium fiber felt—is a critical Gas Diffusion Layer (GDL) and Porous Transport Layer (PTL) for high-performance electrochemical systems. While carbon-based materials are standard for many batteries, titanium felt is required in environments where carbon would oxidize or corrode.
(1) In flow battery application, it serves as a 3D electrode in aggressive chemistries (like Ti-Mn or high-acid Vanadium cells) to improve mass transfer and rate capability.
(2) In electrolyzers, Ti felt is mainly used on the anode (oxygen side) because carbon GDLs oxidize into CO2 at the high potentials required for water splitting. It is also essential for hydrogen production via water electrolysis, providing high surface area for the Oxygen Evolution Reaction (OER).
(3) In fuel cell application field, it acts as a GDL in Unitized Regenerative Fuel Cells (URFC) that both generate and consume hydrogen, providing stability in both modes.
