How to Specify Titanium Fiber Felt for PEM Electrolyzers

Thickness & porosity: 0.25–1.0 mm at 60–70 % porosity; thinner felts lower ohmic loss, thicker felts spread current better.
Coating: Platinum or iridium flash keeps titanium oxide from raising contact resistance over time.
Tolerance & flatness: Tight thickness tolerance so the membrane is compressed evenly across the cell.

Materials

Standard supply is stainless steel 316/316L; the material column in the table and the drawing options show the exact grade for each size. Other alloys and finishes can be quoted to your drawing.

Fitting & Care

Cut with clean, sharp tools in a clean area so metal burrs cannot pierce the membrane.
Torque stack bolts in steps to compress the felt evenly.

Common Mistakes

Using uncoated felt on the anode, which passivates and raises cell voltage over time.
Uneven compression that leaves hot spots and membrane thinning.

When Titanium Fiber Felt for PEM Electrolyzers Is Not the Right Choice

Not for alkaline electrolyzers, which use nickel mesh or foam instead of titanium.

Frequently Asked Questions

What is Titanium Fiber Felt for PEM Electrolyzers used for?

Acting as the porous transport layer in PEM water electrolyzers, where sintered titanium fiber felt carries water to the anode catalyst, lets oxygen escape and conducts current to the bipolar plate.

What is a porous transport layer in a PEM electrolyzer?

The porous metal layer between catalyst and bipolar plate that moves water in, oxygen out and current through.

Why is titanium used for PEM electrolyzer PTLs?

It survives the high anode potential and acidity where steel would corrode.

Does titanium felt need a coating?

A platinum or iridium flash is recommended to keep contact resistance low.
