Effect of Sm-doping on the hydrogen permeation of Ni-La2Ce2O7 mixed protonic-electronic conductor

Journal Article


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-La2-xSmxCe2O7 (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-La1.95Sm0.05Ce2O7 possessing the highest hydrogen permeation fluxes. © 2010 Professor T.
