Filed:

Aug 27, 2002

Appl. No.:

10/064886

Inventors:

Richard Scott Bourgeois - Albany NY, US
Anthony Mark Thompson - Niskayuna NY, US
Curtis Alan Johnson - Niskayuna NY, US

Assignee:

General Electric Company - Niskayuna NY

International Classification:

H01M 214

US Classification:

429 38, 429 30, 429 34, 429 35

Abstract:

A fuel cell stack includes at least one fuel cell unit and a number of interconnects defining at least two openings and including at least one flow field for flowing a reagent. Each opening defines a respective fuel manifold, including at least one each of intake and exhaust fuel manifolds. The fuel cell unit includes an anode, a cathode, and an electrolyte disposed therebetween. The anode is adjacent to and in both electrical connection and fluid communication with one of the interconnects, which has a flow field that guides a fuel flow between the intake and exhaust fuel manifolds. The cathode is adjacent to and in both electrical connection and fluid communication with another interconnect with a flow field that guides an oxidant flow. The fuel cell stack includes a perimeter isolation seal and at least two interior isolation seals for sealing the electrolyte to the respective interconnects.

International Classification:

H01M008/04
B05D005/12

US Classification:

429037000, 429066000, 429026000, 427115000

Abstract:

A fuel cell assembly comprises a stress inducer for inducing a planar compressive stress, typically at least one stress inducer, in some embodiments, to at least one of an anode layer, a cathode layer and an electrolyte layer interposed therebetween, constructed from brittle layers having a higher fracture strength in compression than in tension. More particularly, the present technique provides a stress inducer for inducing the planar compressive stress to at least one of those brittle layers.

US Classification:

1741251, 29599, 29868

Abstract:

Method for joining wires using low resistivity joints is provided. More specifically, methods of joining one or more wires having superconductive filaments, such as magnesium diboride filaments, are provided. The wires are joined by a low resistivity joint to form wires of a desired length for applications, such in medical imaging applications.

US Classification:

428335

Abstract:

A composite that protects thermal barrier coatings from the deleterious effects of environmental contaminants at operational temperatures is discovered. The thermal barrier coated parts have least two outer protective coatings that decrease infiltration of molten contaminant eutectic mixtures into openings in the thermal barrier coating.

International Classification:

B32B 1504

US Classification:

428469

Abstract:

A composite that protects thermal barrier coatings on parts from the deleterious effects of environmental contaminants at operating temperatures with an impermeable barrier coating is divulged. The thermal barrier coating composite decreases infiltration of molten contaminant compositions into openings in the thermal barrier coating to increase the life of the composite.
