HYDROGEN SEPARATION PERMEABLE MEMBRANE EXHIBITING EXCELLENT HYDROGEN SEPARATION PERMEABLE FUNCTION FOR LONG DURATION BY HIGH-PRESSURE OPERATION OF APPARATUS FOR HIGHLY-PURIFYING AND REFINING HYDROGEN

摘要

PPROBLEM TO BE SOLVED: To provide a hydrogen separation permeable membrane which exhibits excellent hydrogen separation permeable function for a long duration by high-pressure operation of an apparatus for highly purifying and refining hydrogen. PSOLUTION: The hydrogen separation permeable membrane of an apparatus for highly purifying and refining hydrogen is made of an amorphous Ni-Zr-Ti alloy with a composition containing 15 to 37% by atom of Zr; 20 to 37% by atom of Ti; and balance Ni and inevitable impurities (37 to 57% by atom of Ni).
