A core construction for a fuel cell is disclosed having both parallel and cross flow passageways for the fuel and the oxidant gases. Each core passageway is defined by electrolyte and interconnect walls. Each electrolyte wall consists of cathode and anode materials sandwiching an electrolyte material. Each interconnect wall is formed as a sheet of inert support material having therein spaced small plugs of interconnect material, where cathode and anode materials are formed as layers on opposite sides of each sheet and are electrically connected together by the interconnect material plugs. Each interconnect wall in a wavy shape is connected along spaced generally parallel line-like contact areas between corresponding spaced pairs of generally parallel electrolyte walls, operable to define one tier of generally parallel flow passageways for the fuel and oxidant gases. Alternate tiers are arranged to have the passageways disposed normal to one another. Solid mechanical connection of the interconnect walls of adjacent tiers to the opposite sides of the common electrolyte wall therebetween is only at spaced point-like contact areas, 90 where the previously mentioned line-like contact areas cross one another.

A fuel cell, comprising the combination of a core having a plurality of electrolyte and interconnect walls arranged to define a plurality of flow passageways, each electrolyte wall having cathode and anode materials sandwiching an electrolyte material, each interconnect wall having cathode and anode materials sandwiching an inert support material and many spaced small plugs of interconnect material extended therethrough which electrically connect the cathode and anode materials together, the walls being arranged whereby only anode material defines one set of the passageways suited for the fuel and whereby only cathode material defines another set of passageways suited for the oxidant, each interconnect wall being wavy and extended between adjacent pairs of generally parallel electrolyte walls and being proximate one another along spaced generally parallel line-like contact areas operable to define one tier of generally parallel alternately adjacent flow passageways for the fuel and oxidant gases, and alternate tiers of the passageways being arranged to have the passageways disposed transverse to one another, whereby the interconnect walls of adjacent tiers connect to the opposite sides of the common electrolyte wall therebetween only at spaced point-like contact areas where the previously mentioned line-like contact areas cross one another.
