US Patent:

20070037021, Feb 15, 2007

Filed:

Oct 23, 2006

Appl. No.:

11/585443

Inventors:

Peter Szrama - Newark DE, US
James Lagrant - Oxford PA, US

International Classification:

H01M 8/00

US Classification:

429012000

Abstract:

An assembly for use in a fuel cell comprising a first membrane having an inner portion and an outer peripheral portion; a second membrane having a corresponding inner portion to the inner portion of the first membrane, and a corresponding outer peripheral portion to the outer peripheral portion of the first membrane; a structural film layer disposed between at least part of the outer peripheral portion of first membrane and the corresponding outer peripheral portion of the second membrane; and the inner portion of the first membrane contacting the corresponding inner portion of the second membrane to provide ionic communication between the first membrane and the second membrane. The structural film provides added strength and stability to the assembly.

Anton Killer - Dietramszell, DE

International Classification:

H01M 8/10

US Classification:

429 30

Abstract:

A catalyst coated membrane assembly comprising a solid polymer electrolyte membrane, an electrode that covers substantially one entire face of said solid polymer electrolyte membrane, and a structural film layer attached to at least two opposing outer regions of said electrode such that it partially overlaps the open face of said electrode. The use of structural film layer allows for high volume, high yield manufacturing of assemblies, leading to reduced assembly cost.
