    Abstract: An apparatus and method for measuring the quantity of hydrogen in a hydrogen storage vessel (300) of a hydrogen fuel cell using the Pressure, Composition, Temperature (PCT) relationship (350) of the storage media is disclosed. The method of measuring the quantity of hydrogen (360) 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 walls of the hydrogen storage vessel, computing the pressure (330) inside the vessel based on the strain measurements, referring to a look-up table (340) with PCT graph/operating curve data (350) or an equation using Van't Hoff parameters for representing the discharge PCT curve for the particular concentration at the measured pressure. The changes in temperature and pressure during hydrogen absorption-desorption which are characteristic of hydride composition is used to measure the concentration ratio of hydrogen to metal hydride as a concentration ratio of hydrogen to metal.

    Abstract: Rewritable signs (100, 1300) that include bistable cholesteric liquid crystal layers (102, 1402, 1404, 1406) are provided. According to one embodiment a rewritable sign (100) is devoid of circuitry for establishing electric fields in localize regions for writing information to the rewritable sign (100), and is consequently inexpensive. In the latter embodiment, a separate information writer (400) that includes an array of pixel electrodes (404) that is driven by an active matrix (602) is used to write information on the rewritable sign. According to another embodiment a rewritable sign (1300) includes three cholesteric liquid layers (1402, 1404, 1406) each of which reflects a different primary color. The three cholesteric liquid crystal layers (1402, 1404, 1406) are interleaved with sets of conductive lines (1316, 1320, 1322, 1324) that are used to apply signals to the cholesteric liquid crystal layers (1402, 1404, 1406) for the purpose of writing information.

    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: 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.
