    摘要: A composite sealant for in-situ sealing a fuel cell stack is provided. A paste of the sealant mixture is initially formed by mixing a glass precursor powder and a reacting filler material. The sealant mixture paste is applied to selected sealing locations of the fuel cell stack. The sealant mixture paste is then transformed into a composite sealant material to seal the selected sealing locations by heat treatment in air to about 900° C. The composite sealant material comprises a glass matrix phase and a reinforcing phase including a plurality of interlocked elongated single crystal grains. The reacting fillers modify the CTE and significantly improve the gap filling capacity of the composite sealant material and provide superior pressure containment capability at elevated temperatures.

    摘要: A sealless, planar fuel cell stack system, including a continuous bottom plate, a first permeable or interconnect layer, a continuous cell, a second permeable or interconnect layer, a continuous top plate, a fuel supply member, and an oxidant gas supply member, is provided. The fuel cell system of the present invention does not require glass-based sealants to seal its planar components. In the present system, the continuous cell of the system is supported by the first permeable layer. The second permeable layer is supported by the continuous cell. The fuel supply member supplies fuel into the first permeable layer. The fuel supply member extends between an outer edge and a center region of the first permeable layer and allows distribution of the fuel in a radial fashion. Further, the fuel supply member is connected to an external fuel manifold adjacent the outer edge. The oxidant gas supply member supplies oxidant gas into the second permeable layer. The oxidant gas supply member extends between an outer edge and a center region of the second permeable layer and allows distribution of the oxidant gas in a radial fashion. The oxidant gas supply member is connected to an external oxidant gas manifold adjacent the outer edge.

    摘要: An assembly for preventing a fire resulting from the outgassing of a lithium battery in an electronic door lock includes a lithium battery, a circuit board, and a thermal insulation. The lithium battery and circuit board are housed within the electronic door lock. The thermal insulation is arranged between a door interfacing side of the electronic door lock and either or both of the circuit board and lithium battery. Another thermal management technique for preventing fire resulting from the outgassing of a lithium battery in an electronic door lock is achieved by using a battery cover that is selectively movable away from the circuit board or ignition source in response to temperature rise to ensure the lithium battery does not reach a critical temperature that may cause outgassing in close proximity to the ignition source.
