Abstract: A glass ceramic composition for sealing adjacent metal cassettes in an SOFC stack. The seal composition comprises an alumina-silicate glass ceramic matrix or a matrix of Zr2 and a ceramic fiber aggregate and non-fibrous zirconia dispersed in the matrix. Preferably, the fiber is selected from the group consisting of zirconium oxide fiber, alumina fiber, and combinations thereof. Preferably, the fiber is present at 1-60 weight percent with respect to the weight of glass ceramic, preferably about 30 weight percent. Preferably, the zirconia fiber is stabilized by up to about 10% yttria. Alumina fiber may substitute for a portion of the zirconia fiber. Preferably, the non-fibrous zirconia is present at about 5 weight percent and is also stabilized.

Abstract: An electrically-conductive mesh spacer (42) incorporated into the hydrogen and air gas flow spaces (22,24) between each anode (14) and cathode (16) and its adjacent interconnect (40) in a fuel cell stack (76). The mesh is formed of metal strands and is formed into a predetermined three-dimensional pattern to make contact at a plurality of points on the surfaces of the electrode (14,16) and the interconnect element (40). The formed mesh spacer (42) is secured as by brazing to the interconnect element at a plurality of locations to form an interconnect, which preserves the pattern during assembly of a fuel cell stack (76). The height (48') of the formed pattern is greater than the height of a gas flow space after fuel cell assembly, such that the mesh spacer is slightly compressed (48") during assembly of a fuel cell stack. Because the metal mesh is both compliant and resilient, the compressed spacer (48") is continuously urged into mechanical and electrical contact with its electrode (14,16) over all temperatures and pressures to which the fuel cell assembly may be subjected during use.

Abstract: An electromagnetic fuel injector (100) comprises a body (101) having a fuel inlet (102) and a fuel outlet (103) and a base (104) comprising a valve seat (105) connected to the body (101). A disk-shaped armature (106,301) disposed at the fuel outlet for controlling the flow of fuel has an upper surface (304) and a lower surface (108) that comprises a sealing interface with the valve seat (105). A ring-shaped flexible element (111,302) comprising a plurality of spaced flexible legs (303a,303b,303c) is in contact with the injector body (312) and the upper surface (304) of the armature (106,301) and provides a spring bias between the body (312) and armature upper surface (301). When the injector (100) is closed, spring bias between the body (106,312) and armature upper surface (304) maintains the armature in a sealing position with the valve seat (105), and when the injector (100) is open, increased spring bias between the body (312) and armature upper surface (304) impels the armature (301) to return to a sealing position with the valve seat (105).

Abstract: A solid-oxide fuel cell system having a compact, highly space-efficient basal manifold for conveying high temperature air, exhaust, and hydrogen-rich reformate fuel to and from the core components of the system. The manifold is a three-dimensional assembly of plates and partitioned elements which are easily and inexpensively formed. When assembled, the manifold comprises a network of passageways which allow for the mounting, close-coupling, and integration of critical fuel cell system components, including heat exchangers, a tail gas combustor and fuel reformer, solid-oxide fuel cell stacks, check valves, and oxygen scavengers.

Abstract: A solid oxide fuel cell stack having a plurality of cassettes and a glass composite seal disposed between the sealing surfaces of adjacent cassettes, thereby joining the cassettes and providing a hermetic seal therebetween. The glass composite seal includes an alkaline earth aluminosilicate (AEAS) glass disposed about a viscous glass such that the AEAS glass retains the viscous glass in a predetermined position between the first and second sealing surfaces. The AEAS glass provides geometric stability to the glass composite seal to maintain the proper distance between the adjacent cassettes while the viscous glass provides for a compliant and self-healing seal. The glass composite seal may include fibers, powders, and/or beads of zirconium oxide, aluminum oxide, yttria-stabilized zirconia (YSZ), or mixtures thereof, to enhance the desirable properties of the glass composite seal.

Abstract: A fuel cell cassette (12) for forming a fuel cell stack (10) along a fuel cell axis includes a cell retainer (16), a plate (22) positioned axially to the cell retainer (16) and defining a space axially with the cell retainer (16), and a fuel cell (14) having an anode layer (36) and a cathode layer (34) separated by an electrolyte layer. The outer perimeter of the fuel cell (14) is positioned in the space between the plate (22) and the cell retainer (16), thereby retaining the fuel cell (14) and defining a cavity between the cell retainer (16), the fuel cell (14), and the plate (22). The fuel cell cassette (12) also includes a seal disposed within the cavity for sealing the edge of the fuel cell (14). The seal is compliant at operational temperatures of the fuel cell (14), thereby allowing lateral expansion and contraction of the fuel cell (14) within the cavity while maintaining sealing at the edge of the fuel cell (14).

Abstract: In a solid-oxide fuel cell assembly, a co-flow heat exchanger is provided in the flow paths of the reformate gas and the cathode air ahead of the fuel cell stack, the reformate gas being on one side of the exchanger and the cathode air being on the other. The reformate gas is at a substantially higher temperature than is desired in the stack, and the cathode gas is substantially cooler than desired. In the co-flow heat exchanger, the temperatures of the reformate and cathode streams converge to nearly the same temperature at the outlet of the exchanger. Preferably, the heat exchanger is formed within an integrated component manifold (ICM) for a solid-oxide fuel cell assembly.
