What Is Bubble Point Pressure?

The bubble point pressure is the minimum pressure required to force gas through a wetted membrane pore. It is a direct indicator of the membrane's gas barrier capability: a higher bubble point means the membrane can withstand greater differential pressure between the hydrogen and oxygen sides before gas crosses over.

IONZERA achieves a bubble point pressure exceeding 1.3 bar, compared to greater than 1.0 bar for Zirfon PERL UTP 500. This 30% improvement in gas barrier performance provides an additional safety margin in alkaline electrolysers, particularly during transient operating conditions such as startup, shutdown, and load cycling.

Why Bubble Point Matters for Safety and Purity

In an alkaline electrolyser, hydrogen is produced at the cathode and oxygen at the anode. If these gases mix above certain thresholds, it creates an explosive hazard. The separator membrane is the primary barrier preventing gas crossover. A higher bubble point means the membrane maintains gas separation under a wider range of operating conditions:

Pressure transients during dynamic load following with intermittent renewable energy

Differential pressure spikes during startup and shutdown sequences

Long-term operation where membrane degradation could reduce gas barrier properties

Balancing Pore Size and Gas Barrier Performance

IONZERA's optimized pore size of 0.38–0.42 μm is carefully engineered to balance ion transport (requiring open pores) with gas barrier performance (requiring small pores). The higher bubble point compared to Zirfon demonstrates that IONZERA's pore structure, despite having larger average pore size, has a tighter pore size distribution with fewer oversized pores that would compromise gas separation.
