TECHNICAL SPECIFICATION
PHYSICALUltra-Thin AWE Separator Membrane 350–410 μm
IONZERA is 20–30% thinner than Zirfon PERL UTP 500 while delivering superior mechanical strength. Thinner membranes mean shorter ion pathways, more compact stacks, and lower material costs per cell.

Why Membrane Thickness Matters in AWE
In alkaline water electrolysis, the separator membrane thickness directly influences three critical parameters: ionic resistance (thinner means shorter OH⁻ pathways), stack compactness (thinner allows more cells per stack length), and material cost (less polymer and ceramic per unit area). The ideal membrane minimizes thickness while maintaining mechanical integrity and gas barrier performance.
IONZERA achieves a thickness of 350–410 μm compared to Zirfon PERL UTP 500's nominal 500 ± 50 μm. This 20–30% reduction is enabled by the mesh-free PSU-TiO₂-GO nanocomposite design, which does not require the additional thickness of a PPS mesh reinforcement layer.
Thinner Yet Mechanically Superior
A common concern with thinner membranes is whether they sacrifice mechanical strength. IONZERA decisively refutes this: at 350–410 μm, it achieves a tensile strength of 2.7 MPa versus approximately 2.0 MPa for Zirfon's thicker 500 μm profile. The polysulfone matrix reinforced with TiO₂ nanoparticles and GO nanosheets provides inherent structural integrity without needing a separate mesh layer.
Stack Design Benefits
For electrolyser OEMs, a thinner membrane opens meaningful design possibilities:
- More cells per stack length, increasing hydrogen output per unit of floor space
- Reduced stack weight for easier transport, installation, and maintenance
- Shorter inter-electrode gap for improved current distribution
- Less membrane material required per cell, reducing CapEx per MW
