摘要：
Anode-supported solid oxide fuel cells with a thin layer of proton conducting BaCe0.8Y0.2O3- (BCY) were fabricated by electrophoretic deposition technique using an organic suspension. BCY green films were formed on a graphite-added NiO-BCY substrate. By the classification of particle size distribution by the suitable period of sedimentation yielded a crack-free green film. Sintering of the crack-free green film at 1450 degrees C yielded a dense layer of BCY with the thickness of about 9.2 +/- 0.3 mu m after sintering at 1450 degrees C. The BCY thin film on the NiO-BCY substrate exhibited conductivity of 1.6 x 10(12)S.cm(-1) at 600 degrees C and its activation energy was 0.35 eV. The anode-supported single cell with the BCY thin film resulted in the maximum power density of 74.2mW.cm(-2) at 600 degrees C. (C) 2017 The Ceramic Society of Japan. All rights reserved.
