ABSTRACT OF THE DISCLOSURE A fuel cell battery is disclosed have modules (1) disposed in a stack. Each module comprises a centrally symmetrical electric chemically active plate (2) consisting of an oxide iron-conducting solid electrolyte (2b) and two electrodes (2a, 2c), a gas-tight partition wall (4) between an air space and a fuel space; and a device for conducting air from one peripheral feed point (5) to the centre of the module. At the centre of the module, the air comes into contact with the electric chemically active plates. The device further includes a central supply point (71, 61) for a gaseous fuel. In accordance with the invention, the electric chemically active plates (2) do not have any openings a radial line (6) is provided for the fuel. The fuel can be conveyed through the line from a feed point at the periphery of the module to the central supply point (71, 61) for each module. The invention thus provides a centrally symmetrical fuel cell battery in which the gas and air spaces are reliably separated from one another at the centre. Gas duct seals are no longer required.
