Abstract
The invention provides a fuel cell device including an elongate substrate the length of which is the greatest dimension such that the elongate substrate exhibits thermal expansion along a dominant axis coextensive with the length. A reaction zone is provided along a first portion of the length for heating to an operating reaction temperature, and at least one cold zone is provided along a second portion of the length that remains at a low temperature below the operating reaction temperature when the reaction zone is heated. A plurality of fuel passages and oxidizer passages extend within an interior solid ceramic support structure of the elongate substrate from the cold zone to the reaction zone, each fuel and oxidizer passage having an associated anode or cathode, respectively, in the reaction zone in opposing relation with an electrolyte disposed therebetween that is monolithic with the ceramic support structure.
