ABSTRACT:
A centrally symmetrical fuel cell battery is made of stacked modules each of which has an electrochemical active plate made of one oxide ion conducting solid electrolyte and two electrodes, a gas impervious wall between an air chamber and a fuel chamber, an air conduit from at least one peripheral intake location to a center of the module where the air comes in contact with the electrochemically active plates, and a central supply point for a gaseous fuel. Unlike prior art fuel cell batteries of this type which require seal rings, the fuel cell battery of this application requires no seal rings. The electrochemically active plates are continuous, and supply conduits for the fuel are provided for directing the fuel to each module from at least one intake on the periphery of the module to a central supply point of the module.
