Abstract

The hydrogen permeation behaviors of V₈₅Ni₁₅ and V_84.8Ni₁₅Y_0.2 membranes with palladium coating layers were compared at 480°C, which is considered high temperature for conventional vanadium alloy-based membranes. Although the hydrogen permeability of the V₈₅Ni₁₅ membrane drastically decreased over time, that of the V_84.8Ni₁₅Y_0.2 membrane was sustained for 12 days. The role of yttrium in the membrane was to effectively hinder interdiffusion between the Pd coating layers and the V alloy substrate during hydrogen permeation. The results of the present study provide important clues for the development of hydrogen permeable metallic membranes for high temperature applications.
