摘要： PROBLEM TO BE SOLVED: To provide a brazing material for use in the bonding in atmosphere, which can be melted at a temperature equal to or lower than the melting point of Ag and achieves an improvement in high-temperature durability of a bonded article, and to provide a bonded article and a current collector material having high-temperature durability.SOLUTION: The brazing material for use in the bonding in atmosphere contains Ag, B and Si as essential components, wherein the sum total of the ratios of the contents of the constituent elements other than Ag is set at more than 50% by volume and 90% by volume or less, the ratio of the content of Si in the total content of the constituent elements other than Ag is set at more than 22% by volume, and the ratio of the content of B in the total content of the constituent elements other than Ag is set at more than 14% by volume. For example, as illustrated in Fig.4, in a bonding layer 13 in a bonded test specimen after the retention of a sample at a high temperature, a void 16 (Fig.6) as observed in a bonded test specimen after the retention of a comparative sample is not observed, and it is confirmed that the brazing material is fully melted and good air-tightness can be kept after the retention at a high temperature for a long time.

摘要： PROBLEM TO BE SOLVED: To provide: a brazing material for bonding in atmosphere, which has a low melting point and therefore can have a low bonding temperature in atmosphere without using any flux; a bonded article which is bonded using the brazing material and can have good air tightness and bonding strength; and a current collecting material.SOLUTION: The brazing material for bonding in atmosphere contains Ag and B as the essential components, wherein the content of Ag is, by volume, ≥50% and 8% and ≤50%, and the total amount of Ag, B and inevitable impurities is adjusted to be 100%. The component B is a low melting point material which can be oxidized at about 300°C or higher to produce an oxide having a relatively low melting point (about 577°C). By containing B as the essential component, the brazing material can have a low melting point. For example, as illustrated in Fig.4, a powder of B (reference No. 14) and molten Ag (reference No. 15) are observed in a bonding layer 13 in a bonding test specimen, which demonstrates that the brazing material for bonding in atmosphere has been melted.

摘要： PROBLEM TO BE SOLVED: To provide a solid-oxide fuel cell having improved productivity and reduced cost as well as improved air tightness, durability and heat cycling efficiency; and to provide a method of manufacturing the same. SOLUTION: A fuel cell stack 104 has gas seal parts for sealing spaces between members to prevent gas leakage to the outside. Specifically, the gas seal parts of atmosphere joining brazing materials 131-134 are formed between a power generation cell 102 and a metal cell cover 121, between a metal separator 122 and the metal cell cover 121, between the metal separator 122 and an insulating manifold 142, and between the metal cell cover 121 and the insulating manifold 142. The gas seal parts are joined together in a brazing step using an atmosphere brazing method. COPYRIGHT: (C)2011,JPO&INPIT
