    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: 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: An apparatus and method for measuring the quantity of hydrogen in a hydrogen storage vessel of a hydrogen fuel cell using the Pressure, Composition, Temperature (PCT) relationship of the storage media is disclosed. The method of measuring the quantity of hydrogen involves, measuring the temperature 310 of the hydrogen storage media at one or more points on the hydrogen storage vessel 300, measuring the mechanical strain 320 at one or more points on the hydrogen storage vessel, computing the pressure 330 inside the vessel based on the strain measurements, referring to a lookup table 340 or an equation representing the discharge PCT curve for the particular composition of the hydrogen storage media at the measured temperature and computing the hydrogen concentration at the measured pressure. The changes in temperature and pressure during hydrogen absorption-desorption which are characteristic of hydride storage media air is used to measure the hydrogen concentration in the storage vessel and the hydrogen to metal hydride.

    Abstract: A method (60) of pre-caching user interaction elements, includes monitoring motion patterns (40) with an electronic input device having a gesture recorder and a writing surface using a three-dimensional position of the recorder with respect to the writing surface, analyzing the monitored motion patterns (42) made while the recorder is off the writing surface to determine if the recorder is approaching a target area at the writing surface (44), the target area having an associated functionality, and triggering the functionality (50)before contact between the recorder and the target area. The steps are repeated continuously. The analyzing step (42) determines if the recorder is moving towards the writing surface, and, if so, a two-dimensional location of the recorder with respect to the plane of the writing surface is determined (46) and a trajectory is defined based upon the location and movement of the recorder off the writing surface. A control area disposed at an endpoint of the trajectory is identified (48) as the target area to be triggered. Alternatively, a plurality of trajectories between the recorder and a control area is defined based upon recorder location and movement off the writing surface and correlated with the actual trajectory. For the trajectory with the highest degree of correlation, a corresponding control area is defined as the target area to be triggered. Triggering of multiple control areas can be simultaneous or sequential. The method can be used with a variety of systems including an inductive stylus and tablet system and a radio frequency stylus and tablet system.
