As the water electrolysis industry moves toward higher performance, durability, and commercial-scale manufacturing, optimizing the interface between the catalyst layer and porous transport structure is becoming increasingly important.

ENERICH approaches this challenge through metallic porous-material and interface engineering.

For PEM water electrolysis, ENERICH’s Ti-PTL is manufactured as a monolithic porous titanium structure using a proprietary powder-sintering process. Its controlled and uniform porous architecture is designed to provide reliable transport pathways, stable electrical conduction, and mechanical support at the catalyst interface. The technology also offers flexibility in dimensions, thickness, porosity, and surface configuration to accommodate different electrolyzer designs.

For AEM water electrolysis, ENERICH Ni-mPL™ combines a nickel foam substrate with an integrated microporous nickel layer. This engineered structure creates a finer and more uniform catalyst-facing interface while maintaining the porous transport pathways required for electrochemical operation.

Rather than focusing solely on catalyst materials, ENERICH sees the porous interface itself as an important opportunity for advancing electrolyzer performance. Through precision powder processing, controlled porous structures, and scalable manufacturing, the company works with electrolyzer manufacturers and technology developers to tailor porous transport solutions to specific cell and stack requirements.

ENERICH’s capabilities include large-area manufacturing and customized product configurations, supporting customers from initial material evaluation and prototype development through scale-up toward commercial applications. Both Ti-PTL and Ni-mPL™ reflect the company’s broader expertise in advanced metallic porous materials for clean-energy and electrochemical applications.

At Hydrogen Technology World Expo 2026, visitors will have the opportunity to see ENERICH’s porous transport technologies firsthand and discuss technical requirements directly with the ENERICH team.

“We believe the porous interface is one of the key areas where material engineering can contribute to the next generation of water electrolysis,” said Dr. Man-ho Park, CEO of ENERICH. “We look forward to meeting electrolyzer manufacturers and technology partners in Hamburg and exploring how our porous-material technologies can support their development and scale-up.”
