Tanaka Precious Metal Technologies Develops Low-Temperature Hydrogen Membrane

Tanaka Precious Metal Technologies Co., Ltd. has successfully developed HPM-L111, the world's first metal palladium hydrogen permeable membrane capable of high hydrogen permeation performance at low temperatures around 100°C. This breakthrough significantly reduces the energy required for hydrogen purification, which traditionally needed temperatures of at least 300°C. The HPM-L111 membrane utilizes a proprietary surface treatment technology to create minute jagged structures, increasing the specific surface area and improving hydrogen penetration speed at lower temperatures. This innovation is expected to enhance the accuracy of hydrogen sensors, improve fuel cell efficiency, and facilitate hydrogen removal in vacuum equipment. Sample shipments are scheduled to begin on March 5, 2026, with academic presentations and product showcases planned for March 2026. This development supports the global transition towards a clean and efficient hydrogen society and contributes to carbon neutrality goals.
