Title: Electrophoretic deposition of Y{sub 2}O{sub 3}-stabilized ZrO{sub 2} on the porous La{sub 0.8}Sr{sub 0.2}MnO{sub 3} cathode substrate for SOFC

Abstract

Preparation of YSZ film on La{sub 0.8}Sr{sub 0.2}MnO{sub 3} porous substrate was investigated using electrophoretic deposition (EPD) method. Since the electrical conductivity of La{sub 0.8}Sr{sub 0.2}MnO{sub 3} substrate is satisfactorily high at room temperature, YSZ powders were deposited electrophoretically on La{sub 0.8}Sr{sub 0.2}MnO{sub 3} substrate without any treatment such as metal coating. Open circuit voltage of SOFC where YSZ film prepared by EPD was applied, increased by repeating the deposition and calcination cycles. 6 or more times in repetitions were required to obtain YSZ film without gas leakage. A planar type SOFC fabricated by using Ni as anode, attained an open circuit voltage and maximum power density of 1.0 V and 1.5 W/cm{sup 2}, respectively. It became evident that YSZ films without gas leakage can be prepared by the EPD method on LaMnO{sub 3} cathode substrates.
