Abstract
Hydrogen permeation through SrCe 0.7Zr 0.2Eu 0.1O 3− δ membranes was investigated as a function of temperature, feed H 2O partial pressure, feed H 2 partial pressure and flow rate. Hydrogen permeation flux was proportional to the transmembrane H 2 partial pressure gradient with a 1/4 dependence. A maximum H 2 permeation flux of 0.23 and 0.21 cm 3/cm 2 min was obtained at 900 °C for 100% H 2 and 97 vol% H 2/3 vol% H 2O conditions, respectively. The activation energy decreased with increasing H 2 partial pressure and/or decreasing steam partial pressure. Permeation flux through the SrCe 0.7Zr 0.2Eu 0.1O 3− δ membrane was stable under wet H 2, water gas shift reaction and steam reforming of methane conditions.
