ABSTRACT:
A monolithic mass and energy transfer cell is provided. The cell comprises a monolithic ionically conductive core. The core has an outer surface including a first entrance surface and a first exit surface, which is spaced apart from the first entrance surface. A first set of passages are positioned between the first entrance surface and the first exit surface. The outer surface also includes a second entrance surface and a second exit surface, spaced apart from the second entrance surface. A second set of passages are positioned therebetween. The first set of passages are in a non-parallel relationship with the second set of passages. A first porous, electrically conductive coating is disposed within the first set of passages and a second porous, electrically conductive coating is disposed within the second set of passages. An external electric circuit is in electrical contact with the monolithic ionically conductive core. The monolithic mass and energy transfer cell of the present invention may be used for solid oxide fuel cells, solid electrolyte oxygen pumps and cross-flow electrochemical reactor cells.
