Abstract

A planar fuel cell unit on which a cathode-electrolyte-anode unit (CEA unit), a gas distributor element, inner contacting elements, sealing elements, and an interconnector. The interconnector is formed by a CEA mounting element, a base plate, and a gas distributor element. The CEA mounting element and the base plate are embodied as sheet metal parts that form two shells of a housing and enclose the gas distributor element in a gas-tight manner. Webs that are made of an electrically conductive material are applied to/configured on an external surface of the base plate.
