Abstract

In the present work, effect of Cu alloying in V₉₀Fe₅Al₅ alloy on the hydrogen permeability and malleability was investigated. Addition of Cu to V₉₀Fe₅Al₅ alloy leads to formation of a dual-phase structure consisting of the bcc-(V) and fcc-(Cu) phases. The presence of (Cu) contributes to a significantly improved malleability for producing intact thin foils by cold rolling, leading to enhanced hydrogen permeation flux and efficiency. After cold rolling to a thin foil and subsequent annealing, a hydrogen flux of ~ 40.5 cc H₂ cm^-2min^-1 is obtained for the (V₉₀Fe₅Al₅)₉₀Cu₁₀ membrane of ~ 0.12 mm in thickness at a hydrogen pressure difference of 0.7 MPa at 400 °C. In comparison with V₉₀Fe₅Al₅ membrane, Cu alloyed membranes exhibit enhanced resistance against hydrogen embrittlement and more stable hydrogen permeation flux during long-term permeation.
