The invention relates to a fuel cell system () having at least one or more fuel cells (), wherein the fuel cell () extends between a first cell end () and a second cell end () in a tubular shape, and wherein the fuel cell () is mechanically received with the first cell end () on an inflow distributor unit (), and wherein a fuel gas flows through the fuel cell (), the gas entering the first cell end () and exiting one of the cell ends () as exhaust gas. According to the invention, means () are provided which suction at least a part of the exhaust gas exiting the fuel cell () and feed said gas to the inflow distributor unit () for recirculation.

Fuel cell system having improved fuel gas circulation

A method for production of a solid oxide fuel cell (SOFC) (), having an electrolyte body () with a tubular structure, wherein at least one internal electrode () and one external electrode () are applied to the tubular electrolyte body, with the method having at least the following steps: provision of an injection molding core () on which at least one interconnector material () and the internal electrode () are mounted, arrangement of the injection molding core () in an injection mold (), injection molding of an electrolyte compound () in order to form the electrolyte body (), and removal of the injection molding core () in the form of a casting process with a lost core.
