A solid oxide fuel cell stack includes a plurality of solid oxide fuel cells juxtaposed to one another, with at least two of the cells having a substantially flat configuration; and each of the two cells having an anode layer, an electrolyte layer, and a cathode layer. The fuel stack also includes at least one interconnect disposed among the plurality of cells, with the interconnect being capable of providing an electrical connection between the cells, and the interconnect comprising a plurality of first extensions on a first surface of the interconnect and a plurality of second depressions on a second surface of the interconnect. The first extensions and second depressions are integrally formed with one another to provide a plurality of oxidant passageways and fuel passageways.

[ What is claimed is:] [1.]1. A solid oxide fuel cell stack, comprising:a plurality of solid oxide fuel cells juxtaposed to one another; andat least one interconnect disposed among said cells, said interconnect being capable of providing an electrical connection between at least two of said cells, and said interconnect being configured to provide fuel channels and oxidant channels integrally formed with one another by opposing surfaces of said interconnect such that said fuel channels form and define said oxidant channels and said oxidant channels form and define said fuel channels to eliminate a separately formed layer of fuel or oxidant channels from said stack whereby a fuel and an oxidant flow in a crossflow pattern, coflow pattern, counterflow pattern, and radial pattern through said stack in the absence of changing a configuration of said interconnect.
