Formation of anode supported thin film YSZ electrolyte for ITSOFC by magnetron sputtering in the combination with pulsed electron-beam treatment

Abstract

We describe a method of obtaining anode-supported ZrO2:Y2O3 (YSZ) electrolyte films produced by reactive magnetron sputtering for intermediate temperature solid oxide fuel cell applications. A pulsed electron beam treatment was used as a method of preliminary modification of the porous structure in anode substrates. The influence of this pretreatment on the gas tightness, structural and electrochemical properties of deposited films was studied. It is shown that magnetron sputtering combined with a pulsed electron-beam treatment lead to the formation of deposited YSZ films with a fine microstructure and improvement of electrochemical properties. For the electrolyte thickness about 2.5 μm and the gas permeability value of anode/electrolyte structure of 1.01×10-7 mol/m2s Pa, the maximum power density achieved for a single cell at 800°C and 650°C was found to be 610 and 220 mW/cm2 in air, respectively.
