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.
