US Patent:

7090938, Aug 15, 2006

Filed:

Jan 15, 2003

Appl. No.:

10/342563

Inventors:

Gregory Hilmas - Rolla MO, US
Dustin Beeaff - Rolla MO, US

Assignee:

Curators of the University of Missouri - Columbia MO

International Classification:

H01M 8/02

US Classification:

429 12, 296231

Abstract:

A solid oxide fuel cell having a multichannel electrode architecture and method for preparing the same, the method including forming a first carbon laden composition, including a first thermoplastic binder, into a rod, applying a first zirconia laden composition, including a second thermoplastic binder, onto the rod to form a composite feed rod, extruding the composite feed rod to form a controlled geometry filament, bundling the extruded composite feed rod to form a multicellular feed rod, extruding the multicellular feed rod to form a multicellular rod, cutting the multicellular rod into multicellular discs, applying a zirconia laden material to one surface of a multicellular discs to form a multicellular structure, and heating processing the multicellular structure. The fuel cell is completed by adding anode and cathode materials to the multicellular structure.

B32B025/10

US Classification:

428/297100

Abstract:

A process for continuous composite coextrusion comprising: (a) forming first a material-laden composition comprising a thermoplastic polymer and at least about 40 volume % of a ceramic or metallic particulate in a manner such that the composition has a substantially cylindrical geometry and thus can be used as a substantially cylindrical feed rod; (b) forming a hole down the symmetrical axis of the feed rod; (c) inserting the start of a continuous spool of ceramic fiber, metal fiber or carbon fiber through the hole in the feed rod; (d) extruding the feed rod and spool simultaneously to form a continuous filament consisting of a green matrix material completely surrounding a dense fiber reinforcement and said filament having an average diameter that is less than the average diameter of the feed rod; and (e) arranging the continuous filament into a desired architecture to provide a green fiber reinforced composite.
