    摘要: In one embodiment, a gas sensor element comprises: an electrolyte disposed between and in ionic communication with a first electrode and a second electrode; and a protective layer disposed adjacent to the first electrode. The protective layer comprises a catalytic coating comprising a reducible support material, a catalyst, and a water activator material. The catalyst coating is capable of converting an oxygen consuming species in a gas to an oxygen donating species.

    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.

    摘要: A planar temperature sensing element is provided with first and second layers disposed over the temperature-sensing device. The second layer comprises an inorganic binder, a first ceramic material, and a second ceramic material. The inorganic binder is selected from the group consisting of M3+ phosphates, M4+ phosphates, M3+ nitrates, M4+ nitrates, and combinations comprising at least one of the foregoing. The first ceramic material is selected from the group consisting of aluminosilicate, M3+ aluminates, M4+ aluminates, M3+ hexaluminates, M4+ hexaluminates, and combinations comprising at least one of the foregoing. The second ceramic material comprises a phosphate-containing material.
