Abstract. There is need for efficient energy conversion systems based on domestic fossil or biofuels. Solid Oxide Fuel Cells (SOFC's) are attractive in this case, however sealing is a critical issue in SOFC development. The purpose of this investigation is to find a procedure to seal yttria stabilized zirconia (YSZ) electrolyte to the stainless steel electrical interconnect or gas manifold. The seal is usually exposed to high temperatures in the range of 500 to 1000oC. Brazing by in-situ alloying of nickel and titanium foils was performed to braze zirconia to 444-stainless steel. Different combinations of nickel/titanium foils were used; brazing was done in vacuum at 6 x 10-6 torr at 960°C, 1010, and 1030°C for different brazing times. The braze and interfacial microstructures were characterized by optical microscopy, scanning electron micro

摘要。需要有高效率的能源转换系统立足于国内化石或生物燃料。固体氧化物燃料电池（固体氧化物燃料电池的）有吸引力在这种情况下，但是密封的一个关键问题是在固体氧化物燃料电池的发展。这样做的目的是要找到调查程序印章钇稳定的二氧化锆（ YSZ ）电解质的不锈钢电气互连或天然气多方面的。海豹通常是暴露在高温下的射程为500至1000oC 。钎焊原位合金镍和钛箔进行到钎氧化锆为444不锈钢。不同组合的镍/钛箔使用;钎焊是在真空中在6 × 10-6托在960 ℃ ， 1010年和1030年° C的不同钎次。在钎焊和界面微观结构的特点是光学显微镜，扫描电子显微镜（ SEM ）和能谱（ EDS公司） 。本文评估了工艺参数对的发展和稳定的钎焊金属和相互作用的钎料与两个基板。
