ABSTRACT:
Ceramic membranes with integral seals and support, and related electrochemical cells and cell stacks. The membrane comprises a thin electrolyte layer supported on a porous electrode layer which in turn is supported on a thick ceramic support layer, preferably a ceramic electrolyte support. The support layer is divided into a plurality of self-supporting thin membrane regions by a network of thicker integrated support ribs. The thin electrolyte layer and thick ceramic support layer preferably define a sealing perimeter surrounding the porous electrode layer.
