摘要：

A dense hydrogen permeable composite membranes consisting of Ni and BaCe0.7Zr0.1Y0.2O3-delta (BCZY) were fabricated by a packing method at a lower temperature than the powder-mixing method. The results of backscattered electron microscope (BSEM) and scanning electron microscope (SEM)-energy dispersive analysis system of X-ray (EDS) revealed that the membrane derived from the packing method showed the most uniform mixture of the Ni phase and the BCZY phase. The hydrogen permeation measurement showed that a more uniform microstructure would result in higher hydrogen permeation. (C) 2010 Elsevier B.V. All rights reserved.
