Abstract
In planar Solid Oxide Fuel Cell (SOFC) modules, separation of anode and cathode side gases are achieved by hermetic seals. These seals may be rigid, compressive, or compliant. However, the design of improved sealing materials must address two major challenges: (1) mechanical stability of the seals in the face of thermal cycling and (2) chemical stability with respect to the metallic interconnect. This project will use a composite glass seal to meet the thermal expansion requirements and a spray oxide coating on the interconnect to reduce the reactivity between the glass and the interconnect. Commercial Applications and other Benefits as described by the awardee: The technology should lead to the development of viable sealing solutions for the planar SOFC modules that are preferred for their higher current density. An effective sealing solution would provide an impetus to clean and efficient energy generation.
