Method for producing an SOFC fuel cell

The method involves providing an injection molding kernel (13), on which an interconnector material (14) and an inner-side electrode (11) are applied, where the kernel is made of plastic material. The injection molding kernel is placed in injection molds (25a, 25b). An electrolyte-mass (10a) is injection-molded for formation of an electrolyte body (10). The injection molding kernel is removed according to a type of a casting method such as a thermal method and fusion nuclear technology. The thermal method is implemented by burning of plastic material. An independent claim is also included for a solid oxide fuel cell that is manufactured by the method.
