TANAKA PRECIOUS METAL TECHNOLOGIES Co., Ltd., a company engaged in the industrial precious metals business of TANAKA, announces the successful development of a palladium (Pd) alloy hydrogen permeable membraneoperable in the low temperature range around 300°C. Compared to conventional products, this product features high hydrogen permeation performance while operating at lower temperatures. Provision of this product’s samples is scheduled to start on or after September 15, 2025.
An academic presentation regarding this product will be made at The Japan Institute of Metals and Materials’ “2025 Fall Meeting,” which will be held at Hokkaido University from September 17 to 19, 2025.
Palladium Alloy Hydrogen Permeable Membrane (PdCu39)
Among PdCu alloy membranes, PdCu40 (an alloy with 60% palladium content and 40% copper content) is known to exhibit the highest hydrogen permeation performance. However, hydrogen purification using PdCu40 required operation at high temperatures of around 400°C. TANAKA focused on the palladium content ratio in PdCu-based hydrogen permeable membranes and successfully maximized the performance of PdCu-based hydrogen permeable membranes with PdCu39 (an alloy with 61% palladium content and 39% copper content).
