Dia 40mm titanium fiber felt is made by a special laying process and a special ultra-high temperature vacuum sintering process. Compared with titanium powder sintered plate, Ti fiber felt has an excellent three-dimensional network, porous structure, high porosity, large surface area, uniform pore size distribution, special pressure, and corrosion resistance, and can be rolled and processed. Titanium fiber felts are widely used in aerospace, civil, medical care, and other industries abroad.

Titanium fiber felts are primarily used in electrolyzer stacks as the flow field or diffuser material, particularly on the oxygen (anode) side.  

Features:

has an excellent three-dimensional network porous structure; 

high porosity, several times larger surface area;

uniform pore size distribution, strong corrosion resistance, good water permeability;

high porosity, and heat dissipation;

good performance, high current density, low voltage, stable performance, long life and so on.

Titanium fiber felts are primarily used in electrolyzer stacks as the flow field or diffuser material, particularly on the oxygen (anode) side.  Since electrolyzer hardwares cannot use carbon-based gas diffusion layers (GDLs) at the oxygen evolution electrode due to immediate oxidation of carbon to CO2 (if the medium is acidic) or carbonate ions (if the medium is basic) during the electrolysis reaction, titanium fiber felt becomes an ideal candidate as the diffusion medium and also provide electrical contact between the anode catalyst layer and bipolar plate or current collector component at the anode side. Our titanium fiber felts are produced from small-diameter titanium fibers that has been compressed to flattened form and annealed (i.e., sintered), ensuring a smooth, flat surface suitable for use in electrolyzer.  While the most industrial applications operate their electrolyzers in the anode-fed mode, this product is also an ideal diffusion medium for researchers conducting cathode-fed electrolyzer research.

While the most industrial applications operate their electrolyzers in the anode-fed mode and this product makes an excellent diffusion medium for the oxygen evolution electrode, it can also be used as an ideal diffusion medium for researchers conducting cathode-fed electrolyzer research.

For unitized fuel cells or electrolyzers or regenerative electrochemical devices systems, titanium fiber felt can be used at anode or cathode as the diffusion medium.  Electrochemical oxygen concentrators, electrochemical inerters, certain class of batteries such as redox flow batteries, etc. can also benefit from this product as the diffusion medium regardless of the nature of the reactants.
