In PEM electrolysers, wire mesh serves as the porous transport layer (PTL). It delivers ultra-pure water to the Catalyst Coated Membrane (CCM), ensures uniform gas distribution, and facilitates the efficient removal of oxygen gas at the anode.

Employing specialized materials like titanium provides the high corrosion resistance necessary for demanding system environments. Advanced 3D meshes, similar to the MINIMESH® RPD HIFLO-S, allow for precise control over porosity and flow characteristics.
