ABSTRACT:
A method of manufacturing a solid oxide fuel cell module involves the steps of co-sintering the respective fuel electrodes, and the respective electrolytes, subsequently forming a dense interconnector out of a dense interconnector material, or an interconnector material which turns dense by sintering in at least parts of the solid oxide fuel cell module, in contact with the respective fuel electrodes, and the respective electrolyte, and forming an air electrode on the respective electrolytes before electrically connecting the respective electrodes with the respective first parts of the interconnectors electrically connecting the respective electrodes with the respective first parts of the respective interconnectors via respective second parts of the interconnectors which have a density less than the respective first parts.
