Patent number: 6117288Abstract: An electrochemical device for separating oxygen from an oxygen-containing gas comprises a plurality of planar ion-conductive solid electrolyte plates and electrically-conductive gas-impermeable interconnects assembled in a multi-cell stack. Electrically-conductive anode and cathode material is applied to opposite sides of each electrolyte plate. A gas-tight anode seal is bonded between the anode side of each electrolyte plate and the anode side of the adjacent interconnect. A biasing electrode, applied to the anode side of each electrolyte plate between the anode seal and the edge of the anode, eliminates anode seal failure by minimizing the electrical potential across the seal. The seal potential is maintained below about 40 mV and preferably below about 25 mV. A gas-tight seal is applied between the cathode sides of each electrolyte plate and the adjacent interconnect such that the anode and cathode seals are radially offset on opposite sides of the plate.Type: GrantFiled: May 14, 1998Date of Patent: September 12, 2000Assignee: Air Products and Chemicals, Inc.Inventors: Stuart Adler, Raymond Ashton Cutler, Brett Tamatea Henderson, Jimmy Ludlow, Robin Edward Richards, Dale M.

Patent number: 5750279Abstract: An electrochemical device is disclosed comprising a plurality of planar electrolytic cells connected in series, each cell having an oxygen ion-conducting electrolyte layer, an anode layer and a cathode layer associated with the electrolyte layer, electrically conductive interconnect layers having gas passages situated therein for transporting gaseous streams, which interconnect layers electrically connect the anode layer of each electrolytic cell to the cathode layer of an adjacent planar cell, and sealing means positioned between the interconnect layers and the electrolytic cells to provide a gas-tight seal therebetween. The configuration of the interconnect layer and the placement of the seal means provides a separation between the seal and the conductive pathway of electrons between the anode layer and cathode layer which prevents corrosion or deterioration of the seal.Type: GrantFiled: May 9, 1994Date of Patent: May 12, 1998Assignee: Air Products and Chemicals, Inc.Inventors: Michael Francis Carolan, Paul Nigel Dyer, Eric Minford, Steven Lee Russek, Merrill Anderson Wilson, Dale M.

Patent number: 5681373Abstract: Planar solid-state membrane modules for separating oxygen from an oxygen-containing gaseous mixture which provide improved pneumatic and structural integrity and ease of manifolding. The modules are formed from a plurality of planar membrane units, each membrane unit which comprises a channel-free porous support having connected through porosity which is in contact with a contiguous dense mixed conducting oxide layer having no connected through porosity. The dense mixed conducting oxide layer is placed in flow communication with the oxygen-containing gaseous mixture to be separated and the channel-free porous support of each membrane unit is placed in flow communication with one or more manifolds or conduits for discharging oxygen which has been separated from the oxygen-containing gaseous mixture by permeation through the dense mixed conducting oxide layer of each membrane unit and passage into the manifolds or conduits via the channel-free porous support of each membrane unit.Type: GrantFiled: March 13, 1995Date of Patent: October 28, 1997Assignee: Air Products and Chemicals, Inc.Inventors: Dale M.
