Abstract

The cermet consisting of electronic conductor Ni and proton conductor La₂Ce₂O₇ (LDC) shows good chemical stability but poor hydrogen permeability. In order to improve the hydrogen permeability, novel Ni-La_2-xSm_xCe₂O₇ (x = 0, 0.025, 0.05, 0.075, 0.1 and 0.2) cermets were developed for hydrogen separation. The results show that Sm element doping of LDC can affect the rate of hydrogen permeation, with Ni-La_1.95Sm_0.05Ce₂O₇ possessing the highest hydrogen permeation fluxes.
