Novel in-situ sintering spinel composite cathodes for metal supported SOFCs
Abstract
Metal-supported cells (MSC) for SOFC have attracted growing attention over the last decade, especially for portable and mobile applications. To avoid oxidation of the metal support, sintering steps are typically executed in inert or reducing atmosphere. Standard cathode materials, which are normally used for electrolyte-supported (ESC) or anode-supported (ASC) cells, decompose in such atmospheres. Therefore cathodes should be applied to metal-supported cells only after all the non-oxidizing-atmosphere processing steps are finished. Recently, we have developed new in-situ sintered composite cathodes with sintering temperature < 950 °C. Good adhesion as well as low and long-term stable polarization resistance of new electrodes has been obtained.
