Abstract

A mixed protonic and electronic conductor material BaCe_0.85Tb_0.05Zr_0.1O_3−δ (BCTZ) is prepared and a Ni-BCTZ cermet membrane is synthesized for hydrogen separation. Stable hydrogen permeation fluxes can be obtained for over 100 h through the Ni-BCTZ membrane in both dry and humid conditions, which exhibits an excellent stability compared with Ni-BaCe_0.95Tb_0.05O_3−δ membrane due to the Zr doping.
