Titanium Fiber Felt for PEM Electrolyzers is 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. ISO 22734 electrolyzer stacks is the reference cited for it on drawings, datasheets and purchase orders.
What ISO 22734 electrolyzer stacks Means for Titanium Fiber Felt for PEM Electrolyzers
The dimensions in the table below are supplied to suit ISO 22734 electrolyzer stacks. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.
Titanium Fiber Felt for PEM Electrolyzers Dimensions
| Size | Thickness (mm) | Porosity (%) | Micron rating (u00b5m) | Coating |
|---|---|---|---|---|
| Ti-0.25 | 0.25 | 60 | 20 | None |
| Ti-0.40 | 0.40 | 65 | 30 | Platinum flash |
| Ti-1.00 | 1.00 | 70 | 40 | Iridium / platinum |
Specifying Titanium Fiber Felt for PEM Electrolyzers Beyond the Standard
- 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.
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.
