The centrally symmetrical fuel cell battery is constructed from modules (1) arranged like a stack. Each module has the following components: an electrochemically active plate (2) which consists of a solid electrolyte (2b) (which conducts oxide ions) and two electrodes (2a,2c); a gas-tight separating wall (4) between an air chamber and a fuel chamber; means (3) for passing air from at least one peripheral input point (5) to the centre of the module, where the air comes into contact with the electrochemically active plate; furthermore a central inlet point (71) for a gaseous fuel. …<??>In the case of known fuel cells, the fuel is fed in via a central duct having sealing rings. In the case of the fuel cell battery according to the invention, such sealing rings are no longer necessary: the electrochemically active plates (2) have no perforations and inlet elements (6) for the fuel are provided through which the fuel can be transported for each module (1) from at least one supply point on the periphery of the module to the central inlet point (71). …<IMAGE>… |
