Ti Fiber Felt, Titanium PEM PTL for Fuel Cell

Ti Fiber Felt ， Titanium PEM PTL for Fuel Cell are the main materials in the field of fuel cells industry. 

Ti Fiber Felt, Titanium sintered fiber felt,  is a three-dimoneisonal structure porous material made from titanium fibers through processes such as layering and sintering. It features high porosity, good electrical conductivity, and corrosion resistance, serving as an important base material for manufacturing key components of fuel cells. In fuel cells, it often acts as the core material of the porous transport layer (PTL), providing a structural foundation for gas diffusion, electron conduction, and water management.

Titanium PEM PTL for Fuel Cell Titanium-based Proton Exchange Membrane (PEM) Porous Transport Layer for fuel cells is a key functional component in proton exchange membrane fuel cells (PEMFC) or proton exchange membrane electrolyzers (PEMWE). Leveraging the excellent properties of titanium fiber felt, the titanium-based PTL can operate stably in acidic working environments, with main functions including:

– Supporting the proton exchange membrane to form a reaction interface;

– Conducting electrons to connect the electrode and the current collector; – Promoting the uniform diffusion of reaction gases (such as hydrogen and oxygen) to the catalytic layer;

– Discharging the water generated from the reaction to avoid the “flooding” phenomenon and ensure the efficient operation of the cell.

Its titanium-based characteristics make it particularly suitable for harsh working conditions such as high temperature and high humidity, and it is an important material for improving the power density and durability of fuel cells.
