NOVELTY - An ionically conductive ceramic element (20, 20') comprises tubes (30, 30') each having a closed end (48) and an open end; tube support member receiving open ends of the tubes; first conductive coating formed on the exterior surfaces of the tubes; second conductive coating formed on the interior surfaces of the tubes; and bottom conductive stripes and top conductive stripes connected in such a way that at least one stripe on the top connecting one row of tubes is electrically connected to at least one stripe on the bottom connecting an adjacent row of tubes.    USE - The ceramic element is used to form a component device useful in an oxygen generator or fuel cell assembly (claimed). It may be used to form an Integrated Manifold and Tube (IMAT) module (46).    ADVANTAGE - Symmetry of modular construction of the ceramic element allows a second element to be inverted and sealed to a first element.    DETAILED DESCRIPTION - An ionically conductive ceramic element comprises:    (1) tubes each having interior and exterior surfaces, and each having a closed end and an open end;    (2) tube support member receiving open ends of the tubes, and having a top surface and a bottom surface;    (3) first electrically conductive coating formed on the exterior surfaces of the tubes;    (4) second electrically conductive coating formed on the interior surfaces of the tubes;    (5) at least one bottom electrically conductive stripe formed on the bottom surface of the tube support member to create electrical connections between two or more selected second electrically conductive coatings on the interior surfaces of the tubes; and    (6) at least one top electrically conductive stripe formed on the top surface of the tube support member to create electrical connections between two or more selected first electrically conductive coatings on the exterior surfaces of the tubes; where the top stripes and the bottom stripes are connected in such a way that at least one stripe on the top connecting one row of tubes is electrically connected to at least one stripe on the bottom connecting an adjacent row of tubes.    An INDEPENDENT CLAIM is also included for connecting ionically conductive ceramic elements comprising electrically connecting the top stripes and the bottom stripes in such a way that at least one stripe on the top connecting one row of tubes is electrically connected to at least one stripe on the bottom connecting an adjacent row of tubes.    DESCRIPTION OF DRAWING(S) - The figure is a side view of two IMAT segments or portions with both having the stripe-silver connections sealed together with a glass tape.
