Abstract

Composite membranes based on Ni and Zr-doped BaCeO₃ are promising for hydrogen separation. Such composites show high proton conductivity and adequate chemical stability in H₂O and CO₂, but may be unstable in H₂S. In this work, the hydrogen permeation performance of Ni-BaZr_0.1Ce_0.7Y_0.2O_3-δ was measured in an H₂S-containing atmosphere at 900 °C. The hydrogen permeation flux began to degrade in 60 ppm H₂S and decreased by about 45% in 300 ppm H₂S. After hydrogen permeation tests, X-ray diffraction analysis revealed the formation of BaS, doped CeO₂, Ni₃S₂ and Ce₂O₂S. Analysis of the microstructure and phase composition, and results of thermodynamic calculations suggest that reaction between H₂S and doped BaCeO₃ caused the performance loss of the Ni-BaZr_0.1Ce_0.7Y_0.2O_3-δ.
