    摘要: The torch jet spark plug comprises a shell with an insulator body concentrically disposed within at least a portion of the shell. A pre-chamber is concentrically disposed within at least a portion of the shell and at least a portion of the insulator body, the pre-chamber having an orifice disposed at a first end of the pre-chamber and at an insulator body first end. On at least a portion of a pre-chamber internal surface is an inner electrode comprising up to about 75 vol. % of a bonding agent, about 20 vol. % or greater of a catalytically active material, and about 5 vol. % or greater of a transition metal material. At least partially disposed within a second end of the insulator body, opposite the insulator body first end is an upper terminal. Finally, an upper electrode is disposed within the insulator body, between the inner electrode and the upper terminal, and in a spaced relation to the inner electrode.

    摘要: In a solid-oxide fuel cell assembly comprising a plurality of components having electrically-conductive mating surfaces therebetween, the surfaces are sealed by an electrically insulating gasket that include a mineral composition comprising about 66 mol % MgO and about 33 mol % SiO2, the mineral composition being known mineralogically as forsterite. A brazing alloy may be applied to enhance bonding of the gasket into place. The gasket composition may include additions of Al2O3 to enhance electrical resistivity while having little to no impact of matching expansion coefficients of the gasket and metal mating surfaces. Also, additions such as titania or zirconia to inhibit glassy phase grain boundaries and the formation of impurities and pores in the ceramic grain boundaries may be used. A recommended particle size distribution of precursor powders is disclosed that leads to an optimum microstructure of the sintered gasket.
