Patent ID: 8293426

Claim:
A solid-oxide fuel cell (SOFC) repeat unit in a SOFC stack, the repeat unit characterized by a three-component construct comprising: an oxidation-resistant metal window frame hermetically joined to an electrolyte layer of a multilayer, anode-supported ceramic cell; a pre-cassette comprising a metal separator plate having an insulating layer electrically isolating the separator plate from the window frame and from the ceramic cell, the metal separator plate having a plurality of vias that provide electrical contact between an anode-side current collector within the pre-cassette and a cathode-side current collector of an adjacent cell; and a cathode-side seal; wherein the metal window frame is joined to the pre-cassette to form an SOFC cassette and the cathode-side seal comprises a standoff that supports a cathode channel spacing between each of the cassettes in the stack.
