ABSTRACT:
The invention provides a fuel cell device having first and second cold end regions with a reaction zone therebetween. Fuel and oxidizer inlets are positioned in the first and second cold end regions with respective fuel and oxidizer outlets positioned in either the reaction zone or the opposite cold end region, and respective elongate fuel and oxidizer passages are coupled between the respective inlets and outlets at least partially extending through the reaction zone within an interior solid ceramic support structure in parallel and opposing relation. Electrodes are positioned adjacent the fuel and oxidizer passages in the reaction zone within the interior solid ceramic support structure and are electrically coupled to exterior contact surfaces in at least one of the cold end regions to which electrical connections are made. An electrolyte between the electrodes is monolithic with the interior solid ceramic support structure.
