Support for Planar Solid State Electrochemical Devices

IB-1790

APPLICATIONS OF TECHNOLOGY:

  • Solid oxide fuel cells
  • Gas separation membranes
  • Electrochemical reactors

ADVANTAGES:

  • Allows electrochemical membranes or cells of existing sizes to be used as larger cells or membranes
  • Eliminates the need to make very flat plates with high tolerances at high costs
  • Unit is sealed on the metal support instead of the fragile ceramic cells
  • The electrochemical device can be manufactured separately from the support
 

ABSTRACT:

Craig Jacobson, Steven Visco, and Lutgard DeJonghe have invented a planar system for supporting electrochemical cells or membranes, effectively creating a larger cell. This design sidesteps the expensive proposition of manufacturing large, very flat, thin electrochemical devices.

In this invention, standard sized solid-state devices with dense, thin, electrolyte films are sintered onto perforated metal sheets, metal wire mesh, or porous metal with an interlayer of metal, metal alloy, cermet, or brazing material. The edges of the device are sealed via the metal support instead of the fragile ceramic device.

STATUS: Issued U. S. Patents # 7,232,626 and # 7,829,213 available at www.uspto.gov. Available for licensing.
