Abstract:
Fuel cell components provide fuel cells on a flexible sheet that defines a wall of a flexible plenum. An external support structure limits expansion of the plenum in response to forces exerted by a pressurized reactant. The external support structure may comprise a portion of a housing of a portable device. Cathodes of the fuel cells may be accessible from an outside of the flexible sheet and exposed to ambient air while anodes of the fuel cell are accessible from an inside of the flexible sheet and exposed to a fuel, such as hydrogen gas.
Abstract:
A fluidic control system includes featured layers. The featured layers include two or more features which collectively form at least one functional component.
Abstract:
Methods of manufacturing a fuel cell array that include selectively removing portions of a coating layer from a composite layer. The composite layer includes a first surface and a second surface and a first coating is disposed over at least a portion of the first surface. A laser or mechanical tool is used to selectively remove portions of the first coating to form discontinuity regions at predetermined positions in the first coating.
