Abstract: A fuel cell power source ( 100 ) for use in electronic systems includes a fuel cell system ( 130 ) and a controller ( 150 ). The controller ( 150 ) computes net power requirements of a load device from one or more power functional information sources; and determines an operating point of the fuel cell system ( 130 ) by matching the net power requirements with the power characteristics of the fuel cell system ( 130 ).

Abstract: An apparatus and method for temperature regulation of a fuel cell using differential heat capacity of the fuel storage media is disclosed. The method of regulating the temperature involves measuring the temperature of one or more fuel cells, comparing the temperature against target values, selecting a control method from a set of available control methods based on the result of comparison and using that control method to initiate and control a regulation cycle, and actuating a flow control means using the selected control method to alter the flow of fuel between one or more fuel storage containers, each containing fuel storage media which exhibit different enthalpies of formation and dissociation. The regulation process starts with measuring temperature (110) of a fuel cell system (100). The measured temperature is then compared (120) to a predetermined set of ideal target values designed to provide peak fuel cell performance. Following the comparison step, a control method (130) is selected from a list of available control methods. The control method has the necessary parameters and logic to define an fuel flow initiation process (140) which in turn actuates a flow control means (150). Actuation of the flow control means changes the temperature of the one or more fuel cells and alters its operating parameters (160).

Abstract: Fluxing compositions containing compounds that generate acids upon photoinitiation from a light source such as Hg/Xe ultraviolet (UV) light sources are described. The acids clean oxides from the printed circuit boards (PCBs) under assembly and then volatilize with little or no need for a cleaning step, or cleaning only with water. The compounds that release an oxide removing agent, sometimes called a "photoacid" include metal and organic onium salts and furyl compounds bearing a carbonyl group. Such fluxing compositions can be used mixed with typical solder formulations. such as lead/tin solders, or applied topically thereto; both techniques permit the assembly of PCBs more easily and with high quality bonds.

Abstract: 2063834 9117858 PCTABS00008 Fluxing compositions are described containing as fluxing agents compounds of formula (I), where R is an electron withdrawing group. Im one embodiment, R is selected from the group consisting of fluorine, chlorine, bromine, iodine, sulfur, hydroxyl, nitrile, and benzyl. The compound cleans oxides from the printed circuit boards (PCBs) under assembly and then volatilize with little or no need for a cleaning step, or cleaning only with water of formic acid. Very little or no undesired residue remains, such acid fluxing agents can be used mixed with typical solder formulations, such as lead/tin solder pastes, or applied topically to solder, such as solder balls; both techniques permit the assembly of PCBs more easily with high quality bonds, and with little or no residue. Malic acid is a preferred organic acid fluxing agent.

Abstract: A direct methanol fuel cell system 100 uses dissolved catalyst to promote a fuel cell reaction that takes place in an anode sub-chamber 110 of a fuel cell 102. According to the preferred embodiment the dissolved catalyst comprises a macro cyclic coordinated compound of platinum. The dissolved catalyst is preferably continuously circulated through the anode sub-chamber 110, and is preferably mixed in a mixing valve 118 with methanol and water in order to promote its catalytic action.

Abstract: A fuel cell device has a composite particle electrode ( 200 ) formed using particles ( 210 ) having a combination of ion conductor material, electron conductor material, and catalyst material. Each composite particle ( 210 ) is preferably formed to have a substantially spherical outer layer ( 480 ) of ion conductor material ( 481 ) with conductive and catalyst particles ( 482, 484 ) are dispersed throughout the outer layer ( 480 ). An array of composite particles ( 210 ) is layered in a substantially structured or ordered manner on a membrane support structure ( 220 ) to form the fuel cell electrode. A fuel cell electrode so formed has interstitial gaps between the composite particles that result in a structure permeable to oxygen and other fluids.

Abstract: The fuel cells (110) consists of one or more fuel cells (110), each having a major surface (140), and disposed next to each other in a side-by-side adjacent arrangement and a fuel storage container (120) having an exterior wall (150). The fuel cells (110) are positioned such that distance between t he major surfaces (140) and the fuel storage container wall (150) along a direction normal to the major surfaces is substantially the same. In additio n, one or more of the fuel cells are in thermal contact with the fuel storage container such that cell waste heat is transferred to the fuel storage container. During typical operation, a change in an operational parameter of the fuel cell system such as power output causes a change in the amount of waste heat generated in the fuel cell and the waste heat is transferred to t he fuel storage container.
