Title: A New Technique for Joining Ceramic and Metal Components in High Temperature Electrochemical Devices

Abstract

Coal is a potentially a very inexpensive source of clean hydrogen fuel for use in fuel cells, turbines, and various process applications. To realize its potential however, efficient, low-cost gas separation systems are needed to provide high purity oxygen to enhance the coal gasification reaction and to extract hydrogen from the resulting gas product stream. Several types of inorganic membranes are being developed for hydrogen or oxygen separation, including porous alumina, transition metal oxide perovskites, and zirconia. One of the key challenges in developing solid-state membrane based gas separation systems is in hermetically joining the membrane to the metallic body of the separation device. In an effort to begin addressing this issue, a new brazing concept has been developed, referred to as reactive air brazing. This paper discusses the details of this joining technique and illustrates its use in bonding a wide variety of materials, including alumina, lanthanum strontium cobalt ferrite, and yttria stabilized zirconia.
