Abstract:
1. A method of making a solid oxide fuel cell (SOFC), comprising: providing a solid oxide electrolyte having a first major surface and a second major surface opposite the first major surface and a thickness that is at least 50 microns and less than 150 microns; depositing an anode electrode over the first major surface of the electrolyte; depositing a cathode electrode over the second major surface of the electrolyte to form an electrolyte-supported SOFC, wherein at least one of the anode electrode and the cathode electrode has a total thickness of less than 10 microns and the entire electrode of the at least one of the anode electrode and the cathode electrode is deposited on the electrolyte by physical vapor deposition to produce a solid oxide fuel cell having a planar outer surface defined by the at least one of the anode electrode and the cathode electrode that is deposited on the electrolyte by physical vapor deposition; and incorporating the solid oxide fuel cell into a fuel cell stack wherein portions of the planar outer surface defined by the at least one of the anode electrode and the cathode electrode that is deposited on the electrolyte by physical vapor deposition are in contact with ribs of an adjacent interconnect in the stack and are exposed to gas flow channels defined between the planar outer surface and the ribs of the adjacent interconnect in the stack.
