One of the challenges in manufacturing solid-state electrochemical devices, such as planar solid oxide fuel cells (pSOFC) and oxygen generators, is in hermetically sealing the ceramic and metallic components such that the resulting joint remains rugged and stable under continuous high temperature operation in an oxidizing atmosphere. A well proven method of joining dissimilar materials is by brazing. Unfortunately many of the commercially available ceramic-to-metal braze alloys exhibit oxidation properties which are unacceptable for use in these applications. This paper outlines an alternative brazing technique that is being developed specifically for use in an oxidizing environment.
