Abstract: High-temperature air braze filler materials composed of various ternary metal alloys are described. Noble metals (M) are added as a ternary constituent to a silver-copper oxide (Ag-CuOx) system. The silver (Ag) component is directly substituted with the noble metal to form a series of alloys. Addition of the noble metal increases the solidus and liquidus temperatures of the resulting air braze filler metals and increases temperatures under which seals and other sealing components formed from these filler metals can be employed.

Abstract: High-temperature air braze filler materials composed of various ternary metal alloys are described. Noble metals (M) are added as a ternary constituent to a silver-copper oxide (Ag-CuO x ) system. The silver (Ag) component is directly substituted with the noble metal to form a series of alloys. Addition of the noble metal increases the solidus and liquidus temperatures of the resulting air braze filler metals and increases temperatures under which seals and other sealing components formed from these filler metals can be employed.

Abstract: A seal formed between two parts that will remain gas tight in high temperature operating environments which experience frequent thermal cycling, which is particularly useful as an insulating joint in solid oxide fuel cells. A first metal part is attached to a reinforcing material. A glass forming material in the positioned in between the first metal part and the second part, and a seal is formed between the first metal part and the second part by heating the glass to a temperature suitable to melt the glass forming materials.

A ceramic material may be added to the glass forming materials, to assist in forming an insulating barrier between the first metal part and the second part and to regulating the viscosity of the glass during the heating step.

Abstract: A joint for use in electrochemical devices, such as solid oxide fuel cells (SOFCs), oxygen separators, and hydrogen separators, that will maintain a hermetic seal at operating temperatures of greater than 600°C, despite repeated thermal cycling excess of 600°C in a hostile operating environment where one side of the joint is continuously exposed to an oxidizing atmosphere and the other side is continuously exposed to a wet reducing gas. The joint is formed of a metal part, a ceramic part, and a flexible gasket. The flexible gasket is metal, but is thinner and more flexible than the metal part. As the joint is heated and cooled, the flexible gasket is configured to flex in response to changes in the relative size of the metal part and the ceramic part brought about by differences in the coefficient of thermal expansion of the metal part and the ceramic part, such that substantially all of the tension created by the differences in the expansion and contraction of the ceramic and metal parts is absorbed and dissipated by flexing the flexible gasket.
