Filed:

Aug 9, 2001

Appl. No.:

09/925949

Inventors:

Jeanne S. Pavio - Paradise Valley AZ
Joseph W. Bostaph - Chandler AZ
Allison M. Fisher - Chandler AZ

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H01M 804

US Classification:

429 38, 429 22, 429 30, 429 34

Abstract:

A fuel cell device and method of forming the fuel cell device including a base portion, formed of a singular body, and having a major surface. At least one fuel cell membrane electrode assembly is formed on the major surface of the base portion and includes an electrically conductive hydrophilic material for the wicking of reaction water and providing for electrical conduction to a current collector. A fluid supply channel including a mixing chamber is defined in the base portion and communicating with the fuel cell membrane electrode assembly for supplying a fuel-bearing fluid to the membrane electrode assembly. An exhaust channel including a water recovery and recirculation channel is defined in the base portion and communicating with the membrane electrode assembly and the electrically conductive hydrophilic material. The membrane electrode assembly and the cooperating fluid supply channel and cooperating exhaust channel forming a single fuel cell assembly.

US Classification:

422232000, 429019000

Abstract:

A disposable, compact, and efficient storage apparatus () contains a fuel source () and water for supplying hydrogen fuel () to a micro-fuel cell. The storage apparatus comprises a housing defining a fuel source chamber () and a plurality of water chambers (), and one or more polymer crystals () containing water positioned within each of the water chambers (). The fuel source (), such as a chemical hydride mixed with a catalyst, is positioned within the fuel source chamber (), wherein the water in each of the water chambers () is selectively allowed to migrate to the fuel source chamber () to contact the solid fuel, thereby producing the hydrogen fuel () at a desired flow rate and temperature. A conduit () supplies the hydrogen fuel () produced within the housing to the fuel cell ().

International Classification:

C09J 5/00

US Classification:

156305

Abstract:

A method for forming a housing for an electronic device () includes providing a first rigid layer () including a curved surface defining a cavity (). A first adhesive () is optionally applied over the curved surface, and an electro-optic module () having a flexible substrate and a viewable surface (), is conformally fitted on the first adhesive (). A second adhesive () is optionally disposed over the electro-optic module () and a support structure () is optionally placed on the second adhesive (). The support structure () includes an attachment apparatus () for mounting electronic circuitry. The first and second adhesives () are cured. One of the second adhesive () or both the first rigid layer () and the first adhesive () are transparent for viewing a viewable surface () on or coupled to the electro-optic module ().
