摘要

The synthesis of dense Ce_(1-x)Gd_xO_(2-δ) (CGO) and porous La_(1-x)Sr_xCo_(1-y)Fe_yO_3 (LSCF) electrode thin films was investigated by means of dip- or spin-coating from precursor solutions with mixing nitrates and organic solvent of polyhydroxyl alcohols. The microstructure of the CGO thin films can be changed from dense to porous by changing the species of solvents. The crystallization of the CGO thin film can be enhanced by using polymerized precursor solutions. Dense CGO thin films can be formed directly on porous LSCF substrate with certain surface porosity. The porous LSCF thin films were prepared by using solutions containing the organic solvent, polyethylene glycol. The spin-coated LSCF cathode cell showed higher efficiency for NO decomposition than the platinum-cathode cell.
