Abstract
A fuel cell system has a core in the form of a support having cavities passing therethrough and surfaces on which a multiplicity of fuel cells are disposed and mutually interconnected in series and in parallel by conductor tracks. The support is produced by an extrusion process. The conductor tracks and insulating layers are applied to the surfaces by screen printing and are permanently joined to the support by sintering. The fuel cells are assembled from individual layers and produced by a sheet casting and a screen printing process and are joined permanently to the support by adhesive sintering.
