Abstract: The present disclosure relates to solid oxide fuel cells, and particularly raw powder materials which form a layer in a solid oxide fuel. The raw powder materials include an ionic conductor powder material; and an electronic conductor powder material. The ratio of an average particle diameter of the ionic conductor powder material to an average particle diameter of the electronic conductor powder material is greater than about 1:1, and an average particle diameter of at least one of the electronic conductor powder material or the ionic conductor powder material is coarse.

Abstract: Robust ceramic igniters include an improved sealing system which can significantly enhance operational life of the igniter. Preferred igniters comprise a conductive cold zone (14a, 14b) and hot zone (12) with higher resisitivity. A hermetic sealant material (100) covers one or more electrical connections on each cold zone thereby avoiding igniter failure resulting from electrical shorts and/or undesired oxidation.

Abstract: The present disclosure is directed to an integrated SOFC stack including, a first cell having a cathode layer, an electrolyte layer overlying the cathode layer, and an anode layer overlying the electrolyte layer. The SOFC stack also includes a second cell having a cathode layer, an electrolyte layer overlying the cathode layer, and an anode overlying the electrolyte layer. The SOFC stack further includes a ceramic interconnect layer between the first cell and the second cell, the ceramic interconnect layer having a first high temperature bonding region along the interfacial region between the first cell and the ceramic interconnect layer. The ceramic interconnect layer also includes a second high temperature bonding region along the interfacial region between the second cell and the ceramic interconnect layer.

Abstract: Robust ceramic igniters are provided that include an improved sealing system which can significantly enhance operational life of the igniter. Preferred igniters comprise a conductive cold zone and hot zone with higher resisitivity. A hermetic sealant material covers one or more electrical connections on the of each cold zone, thus shielding the electrical connections from environmental exposure, and thereby avoiding igniter failure resulting from electrical shorts and/or undesired oxidation.
