Abstract

Studies were made on electrochemical behaviors of LaCrO3 based, SrTiO3 based, and CeO2 based oxide anodes. Steady state polarization and AC impedance measurements were carried out in H 2-H2O-Ar gas-mixtures. Electrode microstructure was observed by SEM before and after electrochemical measurements. The CeO 2 based anodes showed higher performance than the LaCrO3 based and the SrTiO3 based oxide anodes. Morphological changes during electrochemical measurements were observed in niobia-doped ceria anodes. Gadohnia-doped ceria anodes showed the highest electrode performance and high redox tolerance. The electrode performance did not show clear relation with the electrode microstructure.
