Abstract: PURPOSE: Hydrogen storage alloys that are coated with hydrogen selective membrane to selectively allow permeation of hydrogen molecular/atom/ion with excluding impurities are provided to prevent poor performance of hydrogen storage alloys according to a prior reaction between hydrogen storage alloys and oxygen/carbon monoxide. The hydrogen storage alloys are expected to exhibit prominent performances in heat pump and thermal storage system. CONSTITUTION: In one embodiment of the present invention, poly ethylene oxide powder is dissolved into acetonitrile, glass-coated, dried in atmosphere and then dried again in a vacuum oven at 60deg.C to obtain a circular transparent PEO polymer film with 95mm in diameter and 14mm in thickness. On the surface of the PEO polymer film TiNi hydrogen storage alloy thin layer is deposited for 1 hr by DC magnetron sputtering method where initial pressure of deposition is about 5x10¬-6 torr, DC voltage is 100watt, sputtering pressure is 2.2x10¬-3 torr, flow rate of Ar is 4 sccm, the distance of target and substrate is 10cm. In the DC magnetron sputtering method a Ti:Ni(60:40, 2inches) substrate is employed as a disc bulk target, wherein temperature of the substrate is kept to be 25deg.C.
