摘要

The Electrophoretic Deposition (EPD) technique has been applied to the preparation of a porous La_0.995Ca_0.005NbO₄/Ni composite anode layer, deposited on a porous pre-sintered La_0.995Ca_0.005NbO₄/Ni support. Powders of La_0.995Ca_0.005NbO₄ and NiO were suspended in a solution of acetylacetone, iodine and water. Selectivity in the composition of the deposited layer was analyzed as a function of the suspension compositions and deposition conditions. A quasi-symmetrical cell was produced by depositing La_0.995Ca_0.005NbO₄ electrolyte layer on the anode layer by EPD, and by applying a porous La_0.995Ca_0.005NbO₄/Ni counter electrode on the dense electrolyte layer by brushing. The performance of the electrodes was evaluated by electrochemical impedance spectroscopy in 3%wet H_2.
