摘要:
The methods include steps for making a fuel cell layer, making a compact chemical reactor with high aspect ratio cavities from components with low aspect ratio cavities, and forming of a high aspect ratio compact chemical reactor using low aspect ratio layers. The methods entail forming at least two process layers; forming a perimeter barrier on at least one side of one of the process layers creating an intermediate assembly with at least one low aspect ratio cavity; repeating the initial steps to create additional intermediate assemblies with at least one low aspect ratio cavity; joining intermediate assemblies to create a compact chemical reactor with high aspect ratio cavities; and joining the compact chemical reactor with high aspect ratio cavities to two reactant plenums to facilitate a transport process between reactant plenums and process layers.

The fuel cell layer with a central axis includes a first and a second unit fuel cell, an oxidant plenum comprising an oxidant; and a fuel plenum comprises a fuel; and each unit fuel cell comprises: a first and second process layer; a first cavity and second cavity formed between the first and second process layer and a first process layer of an adjacent unit fuel cell; a first perimeter barrier disposed on the second process layer substantially surrounding the second cavity; a second perimeter barrier disposed on the first process layer substantially surrounding the first cavity forming a unit fuel cell comprising a front face and back face; the first cavity is in communication with the oxidant plenum; the second cavity is in communication with the fuel plenum; wherein at least one of the process layers transports ions between the first and second cavities.
摘要:
Portable electronic devices such as portable telephones, portable computers and the like may obtain power from fuel cells that consume fuel from fuel stores of the portable devices. A network of refilling stations permits users of portable devices to main the devices operational by frequently topping up the fuel stores. Payment systems combine payments for fuel with larger payments for other transactions to avoid the overhead of processing individual payments for very small amounts.

A sheet of substrate material is corrugated. First and second troughs are defined on opposed faces of the substrate material. Ion-conducting regions are located in a common wall of the first and second troughs. In the ion-conducting regions ions can pass through the substrate material between the first and second troughs.

A method for refilling a hydrogen reservoir comprising a first hydrogen-storing material comprises establishing a fluid connection between the hydrogen reservoir and a cartridge containing a second hydrogen-storing material. The second hydrogen-storing material releases hydrogen at a pressure sufficient to charge the first hydrogen-storing material. Some embodiments involve heating the second hydrogen-storing material and/or allowing heat to flow between the first and second hydrogen-storing materials.
摘要:
A hydrogen source comprises a first hydrogen reservoir for containing hydrogen in a first form and a second hydrogen reservoir for containing hydrogen in a second form different from the first form. The hydrogen source comprises a means for converting hydrogen from the first form to hydrogen gas and transferring the hydrogen gas from the first hydrogen reservoir to the second hydrogen reservoir. An an interface is provided for transferring hydrogen from the second hydrogen reservoir to a hydrogen reservoir in a portable device. The interface comprises a fluidic coupling. The hydrogen source may be used to provide hydrogen fuel to a wide range of portable devices.

摘要:
A power source tester includes a processor and an internal variable load controlled by the processor. A network communication port is coupled to the processor. A pair of inputs is also coupled to the processor for coupling to a power source to be tested under control of the processor. In a method executed by the tester, remote commands are received via a network interface to select one or more tests to be run by the tester. The selected tests are started and data is collected and logged. The data is then sent via the network interface to a remote computer.
摘要:
One aspect of the invention provides an ion-conducting membrane comprising an ion-conducting region and a non-ion-conducting region. The ion-conducting region is formed by a plurality of ion-conducting passageways that extend through the membrane. The passageways are filled with ion-conducting material and may be surrounded by non-ion conducting material. The membrane may comprise a substrate of non-ion-conducting material that is penetrated by openings, each opening providing a corresponding one of the passageways.
