1 mm Titanium Expanded Mesh Conductor for PEM Electrolyzer

1 mm thick titanium expanded mesh used as the rigid current collector and structural support inside industrial PEM water electrolyzer stacks. GR1 titanium with uniform diamond openings delivers low contact resistance, even current distribution and timely bubble release, while resisting the high-potential acidic environment at the anode and the compression loads of stack assembly.

Products Specifications

The 1 mm Titanium Expanded Mesh Conductor is built for industrial-scale PEM water electrolyzer stacks. Made from GR1 pure titanium sheet through precision stamping and integral stretching, the mesh forms uniform diamond openings that combine gas-liquid permeability with the mechanical rigidity required for long-term stack compression. It is the preferred outer current collector and structural support layer for green hydrogen production stacks.

Why 1 mm expanded mesh for PEM electrolyzers?

Thin 0.1–0.5 mm titanium mesh used inside the PTL cannot survive stack clamping pressure at industrial scale. The 1 mm thickness gives rigid structural support that holds the electrode layer flat, protects the MEA membrane from extrusion, and keeps cell-gap tolerances stable — all critical for stack lifetime.
