How to Specify Etched Titanium Porous Plate for Electrolyzers

  • Hole size & pitch: 0.2–0.4 mm holes; pitch sets open area and in-plane conductivity.
  • Thickness: 0.2–0.5 mm Gr1 titanium.
  • Coating: Platinum or iridium flash to keep contact resistance low.

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

  • Handle in clean conditions; contamination poisons catalysts.
  • Compress evenly in the stack.

Common Mistakes

  • Uncoated titanium passivating.
  • Burrs that pierce the membrane.

When Etched Titanium Porous Plate for Electrolyzers Is Not the Right Choice

Not for alkaline electrolyzers, which use nickel.

Frequently Asked Questions

What is Etched Titanium Porous Plate for Electrolyzers used for?

Distributing water and collecting gas in PEM electrolyzer and fuel cell stacks with thin titanium plates etched with thousands of precise through-holes.

Why etched titanium plates?

Precise, burr-free holes in titanium that resist anode corrosion.

Felt or etched plate?

Etched plates give uniform, defined porosity; felt gives higher porosity.

Coating?

Platinum or iridium flash.
