US Patent:

53427050, Aug 30, 1994

Filed:

Jun 4, 1993

Appl. No.:

8/071791

Inventors:

Nguyen Q. Minh - Fountain Valley CA
Timothy R. Armstrong - Pasco WA

Assignee:

Allied-Signal, Inc. - Morris Township, Morris County NJ

International Classification:

H01M 810

US Classification:

429 32

Abstract:

A fuel cell comprises an anode, a cathode, a solid electrolyte disposed between the anode and the cathode, and interconnect means for providing an electrical connection located adjacent to either the cathode or the anode but not adjacent to the solid electrolyte. The interconnect means includes an interconnect layer having a composition of a mixture of an electrical conductor and a ceramic matrix material that is sinterable in an oxidizing atmosphere at a temperature of less than about 1500. degree. C. The interconnect means includes, a first buffer layer having a region with a composition that is intermediate between that of the anode and that of the interconnect layer, a second buffer layer having a region with a composition that is intermediate between that of the cathode and that of the interconnect layer, and the interconnect layer disposed between the first buffer layer and the second buffer layer.

Appl. No.:

7/652341

Inventors:

Timothy R. Armstrong - Palos Verdes Estates CA
John R. Esopa - Hermosa Beach CA
Thomas K. Rigney - Torrance CA
Marshall P. Saville - Torrance CA

Assignee:

Allied-Signal Inc. - Morris Township, Morris County NJ

International Classification:

H02K 2106
F16C 3906
H02N 1504

US Classification:

310 905

Abstract:

A Type II ceramic superconductor is dispersed in an acrylic thermoplastic carrier in a ratio between 1:1 and 3:1. Resulting is a readily formable, thermosetting superconductor composite. The superconductor composite is particularly useful as a magnetic bearing or for fabricating devices to contain magnetic flux, because of its "flux pinning" effect.

US Classification:

310 905

Abstract:

A cylindrical superconductor bearing is made of Type II ceramic superconductor, dispersed in an acrylic thermoplastic carrier in a ratio between 1:1 and 3:1 by volume. The cylindrical superconductor bearing is particularly useful as a magnetic journal bearing.
