Thin films of BaCe{sub 0.8}Y{sub 0.2}O{sub 3-d} (BCY) were prepared by colloidal spray deposition. Dense, crack-free BCY films having a grain size of 2-7 {micro}m were successfully deposited on NiO/BCY substrates. Electrochemical hydrogen pumping with the BCY films showed that the maximum current density increased with temperature. The maximum current density was sensitive to the moisture in the cathode gas; the value obtained with a dry cathode gas was only half that with a wet cathode gas. A very high hydrogen-pumping current density of 3.4 A/cm{sup 2} was measured at 700 C with an applied voltage of 1.5 V.
