Improved Segment-in-Series High Temperature Electrochemical Device

APPLICATIONS OF TECHNOLOGY:

Solid oxide fuel cells Oxygen generators Electrolyzers

ADVANTAGES:

Greatly expands the choice of sealing materials Promises inexpensive manufacturing, high sealing quality, and long lifetime Applicable to devices of any geometry, including planar and tubular Allows alternative electrical and mechanical connection strategies between neighboring devices, manifolds, etc.

ABSTRACT:

Sealing of high temperature electrochemical devices is a major technical barrier to their commercialization. No dominant sealing technology exists; all have drawbacks that have precluded their widespread acceptance.

Berkeley Lab researchers Craig Jacobson and Michael Tucker have invented a seal that overcomes many of the disadvantages of existing seals and sealing methods. The new seal allows manufacturers to choose from a broader array of sealing materials and has other features that may significantly reduce manufacturing costs, improve seal quality, and lead to longer lifetimes. The new seal can be used with almost any conceivable device design and should allow for alternative electrical and mechanical connection strategies between neighboring devices, manifolds, and electrical conduits.
