摘要： A method for improving performance of an SOFC by impregnation of the cathode with metallic silver. A solution of AgNO3 in acetonitrile is imbibed into a perovskite cathode fabricated on a electrolyte layer supported by an anode, defining an SOFC cell. The cathode imbibition may be repeated a plurality of times as may be needed depending upon the thickness of the cathode. The amount of solution soaked into the cathode results a total final weight percent of Ag in the cathode between about 0.5% and about 10%. The cathode is then fired in air at high temperature to drive off the acetonitrile and to reduce the silver ions to metallic silver. In this way, cathode electrical resistance may be reduced by as much as 52%.

摘要： A titania exhaust gas oxygen sensor including an alumina substrate, thin-film electrodes deposited thereon, and a thick-film titania layer deposited atop the electrodes. The electrodes comprise a noble metal (e.g., platinum) having a plurality of titania particles dispersed throughout for promoting bonding to the titania, resistive layer when the titania layer is fired.
