Separate H₂ and O₂
The separator forms the boundary between the cathode and anode compartments, helping limit mixing of the gases produced.
PPS / ENGINEERED FOR ALKALINE ELECTROLYSIS
High-temperature-resistant hydrophilic PPS separators
Woven separators designed for alkaline water electrolysis, with permanent hydrophilicity and a controlled porous structure.
01 / PPS
Keep gases apart.
Let ions move.
Placed between the cathode and anode, the hydrophilic PPS separator keeps the gas-producing compartments apart. Electrolyte wets its porous structure, providing a path for ionic conduction while the woven PPS provides mechanical support.
01
Permanent hydrophilicity
Structural modification supports wetting and electrolyte conduction.
02
Thermal & chemical resistance
PPS materials offer resistance to acids, alkalis, high temperatures and organic solvents.
03
Engineered porous structure
Textile processing and surface control balance gas separation with ion transport.
02 / H₂ │ O₂
What the separator does
Wet with electrolyte
Hydrophilic modification helps the alkaline electrolyte wet the woven PPS and fill its porous structure.
Support ionic conduction
The electrolyte within the pores carries ions between the compartments. The PPS framework provides mechanical support.

Operating conditions
Temperature, electrolyte composition and concentration, differential pressure and current density.
02
Mechanical fit
Active area, sheet dimensions, available thickness and assembly requirements.
03
Supply requirements
Preferred model, sample or production quantity, delivery destination and timeline.
Where is this separator used?
It is designed for alkaline water electrolysis, between the cathode and anode compartments, to help keep hydrogen and oxygen apart.
How do ions pass through the separator?
OH⁻ ions move through the liquid electrolyte held in the porous structure. Ionic conduction is provided by the electrolyte, rather than through the solid PPS polymer itself.
What is the maximum operating temperature?
The available brochure does not specify a maximum continuous operating temperature. The 60 °C resistance test is a test condition, not a temperature limit. Request model-specific confirmation for your application.
How do I choose between JL-450, JL-730 and JL-1100?
Compare thickness, mass per unit area, mechanical properties and area resistance, then review your operating conditions and cell dimensions with our team. The model number alone does not establish suitability.
