  • Capacitive energy storage device and method of producing the same
    Patent number: 6411491
    Abstract: A capacitive energy storage device for use at cryogenic temperatures is provided including first and second electrode layers having a layer of dielectric material there between. The electrode layers include an electrically conductive material having a formula selected from YBa2Cu3Ox and Bi2Ca2Sr2Cu3Oy. A method of storing electrical charge in a capacitive energy storage device is also provided.

  • Combined oxygen and nox sensor
    Publication number: 20020046947
    Abstract: A combined oxygen and NOx sensor is provided. Generally, the combined sensor employs a sensor body that includes two different types of electrodes—oxygen-porous electrode layers and dissociative oxygen-porous electrode layers. In accordance with one embodiment of the present invention, the sensor comprises a sensor body, an oxygen content electrical signal output, and a NOx content electrical signal output. The sensor body is disposed in the gas and comprises a plurality of oxygen-porous electrode layers and a plurality of dissociative oxygen-porous electrode layers. The dissociative oxygen-porous electrode layers comprise a material selected to catalyze dissociation of NOx into nitrogen and oxygen.

  • Ceramic fuel cell
    Patent number: 6372375
    Abstract: A honeycomb ceramic fuel cell is provided including, among other things, (i) an yttria stabilized bismuth oxide oxygen ion conductive ceramic with zirconia incorporated therein, (ii) a niobia stabilized bismuth oxide oxygen ion conductive ceramic, (iii) a copper cermet anode electrode disposed in the fuel supply passage of a bismuth oxide ceramic fuel cell, or (iv) specially arranged inter-passage channels formed in the ceramic body of the fuel cell. In accordance with one embodiment of the present invention, a ceramic fuel cell is provided comprising an oxidant supply passage, a cathode electrode disposed in the oxidant supply passage, a fuel supply passage, an anode electrode disposed in the fuel supply passage, and a stabilized bismuth oxide oxygen ion conductive ceramic interposed between the cathode electrode and the anode electrode. The ceramic may be stabilized with yttria or niobia and may include zirconia.
