Paper Title:
Hydrogen Permeation Performance and Chemical Stability of Ni-La1.95Ca0.05Ce2O7-δ in an H2S-Containing Atmosphere
  Abstract

In this paper, the hydrogen permeation performance of Ni-La1.95Ca0.05Ce2O7-δ (Ni-LDC) was measured in an H2S-containing atmosphere at 1073K. In 75, 150 and 300 ppm H2S, the hydrogen permeation flux decreased by about 5%, 15%, 30% respectively. XRD analysis revealed that sample showed a little formation of Ni3S2, La2O3, LDC, Ni, Ce2O2S. Based on the analysis of the microstructure and phase composition, and results of thermodynamic calculation, we suggested that the reaction between H2S and CeO2 is main cause of hydrogen permeation performance of the Ni-La1.95Ca0.05Ce2O7-δ cermet lossing.
