Abstract
A method of fabricating a SSZ/SDC bi-layer electrolyte solid oxide fuel cell, comprising the steps of: fabricating an NiO-YSZ anode substrate from a mixed NiO and yttria-stabilized zirconia by tape casting; sequentially depositing a NiO-SSZ buffer layer, a thin SSZ electrolyte layer and a SDC electrolyte on the NiO-YSZ anode substrate by a particle suspension coating or spraying process, wherein the layers are co-fired at high temperature to densify the electrolyte layers to at least about 96% of their theoretical densities; and painting/spraying a SSC-SDC slurry on the SDC electrolyte to form a porous SSC-SDC cathode. A SSZ/SDC bi-layer electrolyte cell device and a method of using such device are also discussed.
