抄録

A five-layered membrane composed of an amorphous Ni-Nb-Zr alloy substrate (ca. 30μm), thin proton-electron mixed conductive tungsten phosphate glass films (ca. 50 nm) and Ni coatings (ca. 20 nm) was fabricated by pulsed laser deposition and vacuum evaporation. A flux of hydrogen passed through the laminated membrane without Pd at 673 K at ca. 2 × 10 -6 mol-cm -2·s -1, and no degradation was observed in the 10h operation. The present results suggest that amorphous Ni-Nb-Zr alloy passivated with WO 3-based oxide glass is a promising material for H 2 filtering in a medium temperature range.
