Abstract
A dense ceramic electrolyte membrane supported by symmetrical porous ceramic electrolyte layers. The thin (t<100 microns) electrolyte layer is sandwiched between two fugitive-containing electrolyte support layers that become highly porous after firing. The heat treated fugitive-containing support layers form a skeletal structure of strongly adhered electrolyte with an interpenetrating network of pores that extends well always from the electrolyte surface. The porous layers can be infiltrated with a range of electrode materials or precursors to form a solid oxide fuel cell or other electrochemical cell as well as electrochemical cell stacks. The supported ceramic membrane provides electrochemical performance advantages and reduces warpage during sintering compared to conventional structures.
