Summary

A significant challenge in developing and manufacturing planar solid oxide fuel cells is in hermetically sealing the electrochemically active ceramic PEN to the metallic body of the device. One means of doing this is by chemically bonding the electrolyte surface of the PEN to the metal frame, thus forming a fixed or static seal. Typically a glass or glass-ceramic material is used in making this type of seal. However because of their brittle nature, there are number of manufacturing and operational problems that are encountered when using these materials. In an effort to efficiently screen potential solutions to these problems, a seal rupture test was developed. Details of the test procedure, the test device, and its use in thermal cycle testing various planar solid oxide fuel cell sealing concepts will be discussed.
