Disclosed herein are manifolding means for directing the fuel and oxidant gases to parallel flow passageways in a fuel cell core. Each core passageway is defined by electrolyte and interconnect walls. Each electrolyte and interconnect wall consists respectively of anode and cathode materials layered on the opposite sides of electrolyte material, or on the opposite sides of interconnect material. A core wall projects beyond the open ends of the defined core passageways and is disposed approximately midway between and parallel to the adjacent overlaying and underlying interconnect walls to define manifold chambers therebetween on opposite sides of the wall. Each electrolyte wall defining the flow passageways is shaped to blend into and be connected to this wall in order to redirect the corresponding fuel and oxidant passageways to the respective manifold chambers either above or below this intermediate wall. Inlet and outlet connections are made to these separate manifold chambers respectively, for carrying the fuel and oxidant gases to the core, and for carrying their reaction products away from the core.

A fuel cell for electrochemically combining fuel and oxidant for generation of galvanic output, comprising the combination of a core having an array of electrolyte and interconnect walls, each electrolyte wall consisting of cathode and anode materials respectively sandwiching electrolyte material therebetween and each interconnect wall consisting of the cathode and anode materials respectively sandwiching interconnect material therebetween, the array providing that separate sections of each electrolyte wall are arranged between separate sections of adjacent pairs of interconnect walls operable to define a plurality of substantially parallel core passageways alternately arranged respectively where the inside faces thereof are formed either of only the anode or cathode material, each anode material passageway being for the fuel and each cathode material passageway being for the oxidant, means to direct the fuel and the oxidant for separate flow through each of its respective passageway, said last mentioned means including intermediate wall means extended from the electrolyte wall in the general direction of the passageways and each being spaced generally between the adjacent interconnect walls operable to define thereby separate end chambers open to the respective passageways, duct means for inputting the fuel and oxidant to the appropriate end chamber, and means to direct the galvanic output from the anode and cathode materials to an exterior circuit.
