TANAKA Develops World's First Low-Temperature Palladium Hydrogen Permeable Membrane
TANAKA PRECIOUS METAL TECHNOLOGIES has developed HPM-L111, the world's first palladium hydrogen permeable membrane for high-performance hydrogen purification at temperatures around 100°C. Scheduled for sample shipments starting March 5, 2026, this innovation reduces energy consumption and supports the hydrogen ecosystem. The membrane's surface treatment enhances hydrogen permeation speed, making it applicable in hydrogen sensors and fuel cells, contributing to carbon neutrality by eliminating the need for high-temperature operations.

TANAKA PRECIOUS METAL TECHNOLOGIES announced the development of HPM-L111, a palladium hydrogen permeable membrane that operates effectively at low temperatures around 100°C, enabling high-purity hydrogen purification. Sample shipments will begin on March 5, 2026, with a production capacity of approximately 100 samples per month.
The membrane features a specially treated surface that increases hydrogen penetration speed, overcoming the limitations of traditional metal membranes that require over 300°C. Potential applications include hydrogen sensors and fuel cells, and it is expected to reduce energy for heating, supporting carbon neutrality efforts.
