摘要：
We developed environmental-friendly co-sintering processing technology of electrolyte/anode layers in solid oxide fuel cells (SOFCs) using several different types of nano-powders and water-based slurry. The shrinkages of Ce0.9Gd0.1O1.95(CGO) nano-powder for electrolyte and NiO-CGO nano-powder for anode substrate matched each other after the appropriate material selection and the optimization of pre-treatments. Next, the water-based CGO slurry was developed for electrolyte thin film formation. By effect of an emulsion type binder and lemon pectin, the water-based CGO slurry which has the both adhesive strength and stability was obtained. Finally, a dense and thin CGO film was formed on the NiO-CGO anode substrate by co-sintering process at 1400 degrees C, and the prepared film thickness was ca. 8 mu m.
