Zirfon PERL UTP 500 Specifications vs IONZERA

Selecting the right separator membrane for alkaline water electrolysis (AWE) requires careful evaluation of technical specifications. Every parameter - from area resistance to pore size - directly impacts electrolyser efficiency, hydrogen purity, and total cost of ownership.

Below, we present a complete specification comparison between IONZERA and the industry-standard Zirfon PERL UTP 500, covering all key datasheet parameters that electrolyser designers and procurement teams evaluate.

Area resistance is the single most important specification for AWE separators because it directly determines the voltage drop across the membrane and, consequently, the energy consumption per kilogram of hydrogen produced.

IONZERA achieves an area resistance of 0.09-0.1 Ω·cm² in 30 wt% KOH - approximately 3x lower than Zirfon's 0.30 Ω·cm². This translates to significantly lower cell voltage and reduced electricity costs over the electrolyser's lifetime.

At 350-410 μm, IONZERA is 20-30% thinner than Zirfon's 500 ± 50 μm while maintaining superior mechanical strength (2.7 MPa vs ~2.0 MPa). This is possible because IONZERA uses a mesh-free design with an optimized PSU-TiO₂-GO nanocomposite structure.

IONZERA's higher porosity (55-65% vs 50-55%) combined with optimized pore size (0.38-0.42 μm) and graphene oxide nanosheets creates superior ion transport pathways. The result is lower ionic resistance without compromising gas separation performance.
