The point of current interest in producing hydrogen from a product gas of biofuels reforming is design of hydrogen separation membranes. Nanocomposites with a high mixed ionic (protonic) - electronic conductivity are known to be promising materials for this application. This work aims at design and performance of hydrogen separation membranes based on NiCu/Nd5.5WO11.25-δ nanocomposite. Individual nanocrystalline oxides Sm0.15Pr0.15Ce0.35Zr0.3O2-δ and Ni0.5Cu0.5O were synthesized by modified Pechini route. Nd5.5WO11.25-δ was synthesized by a citrate method with microwave irradiation. Nanocomposites NiCu/Nd5.5WO11.25-δ (70 wt. %) were prepared by the mechanical treatment in a planetary ball mill. A few dense NiCu/Nd5.5WO11.25-δ functional layers (total thickness ~ 150 μm) were deposed on the NiAl alloy foam substrate (diameter ~ 35 mm, thickness ~ 4 mm). Porous Ru+Ni/Sm0.15Pr0.15Ce0.35Zr0.3O2-δ catalytic layers were consecutively deposed on the membrane fuel side and sintered at 900 °C. The membrane performance was tested on a specially built setup. A promising for the practical application performance was achieved by conducting ethanol steam reforming reaction in the temperature range of 400 – 900 °C and at C2H5OH content up to 10 %, H2O/EtOH ratio 1-4 and feed rate up to 7 L h-1. Complete EtOH conversion was achieved at T ~ 700 °C. A high hydrogen permeation flux of 1 – 4 mL H2 cm-2 min-1 was revealed. These permeation characteristics are provided by a high protonic mobility of the material (DH ~ 10-11 cm2 s-1, Dchem ~ 10-3 cm2 s-1 at 400 °C). The curve fit function was applied to simulate the results of membrane operation by using a phenomenological model based on the Arrhenius law. The mathematical model describing this membrane operation has been developed
