Separate H₂ and O₂
The separator forms the boundary between the cathode and anode compartments, helping limit mixing of the gases produced.
ENGINEERED FOR ALKALINE ELECTROLYSIS
PPS separators.
Built for hydrogen.
High-temperature-resistant hydrophilic PPS separators for alkaline water electrolysis. A porous, woven layer between the electrodes that separates hydrogen and oxygen while supporting ionic conduction through the electrolyte.

01 / PPS
High-temperature-resistant hydrophilic PPS separators
Woven separators designed for alkaline water electrolysis, with permanent hydrophilicity and a controlled porous structure.
JL-450 / PPS01 / INSIDE THE ELECTROLYZER
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.

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.
