PPS Membrane - High Gas-Tight Separator for Alkaline Water Electrolysis
Industry-Leading Gas Tightness · Permanent Hydrophilic Technology · Ultra-Low Area Resistance
Market Background
Driven by carbon neutrality goals, China's hydrogen industry is rapidly developing, with green hydrogen production becoming a key pathway for renewable energy utilization. According to the "Medium and Long-term Plan for Hydrogen Industry Development", renewable hydrogen production will reach 100,000-200,000 tons/year by 2025.
As a core material for alkaline water electrolysis, membrane demand is growing rapidly. The membrane market is expected to exceed 220,000-440,000 m² by 2025. Compared to composite membranes, PPS membranes offer significant advantages in cost and mechanical strength, dominating alkaline electrolyzers.
