Patent ID: 7427339

Claim:
An electrochemical device comprising: (a) a first solid electrolyte having an anode side, a cathode side and an outer edge; (b) a first anode situated adjacent to the anode side of the first solid electrolyte, the first anode having an outer edge wherein the outer edge of the first anode is offset from the outer edge of the first solid electrolyte; (c) a first cathode situated adjacent to the cathode side of the first solid electrolyte, the first cathode having an outer edge wherein the outer edge of the first cathode is offset from the outer edge of the first solid electrolyte; (d) a second solid electrolyte having an anode side, a cathode side and an outer edge; (e) a second anode situated adjacent to the anode side of the second solid electrolyte, the second anode having an outer edge wherein the outer edge of the second anode is offset from the outer edge of the second solid electrolyte; (f) a second cathode situated adjacent to the cathode side of the second solid electrolyte, the second cathode having an outer edge wherein the outer edge of the second cathode is offset from the outer edge of the second solid electrolyte; (g) an electrically-conductive, non-ionically conductive ceramic interconnect having no connected through porosity situated between said first solid electrolyte and said second solid electrolyte, said interconnect having an anode side, a cathode side, and an outer edge; and (h) a layer located between the outer edge of the interconnect and at least one of the outer edge of the first anode, the outer edge of the first cathode, the outer edge of the second anode, and the outer edge of the second cathode, said layer comprising at least one metal selected from the group consisting of silver, gold, platinum, rhodium, and palladium; wherein the layer is in physical contact with at least 75% of at least one of the anode side of the interconnect and the cathode side of the interconnect.
