    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: A method for humidifying a fuel stream for a direct methanol fuel cell. An ultrasonic transducer (122) is used to create a vapor of methanol without heating. Water is also vaporized with an ultrasonic transducer (132) to create a vapor of water without heating. The water vapor and the methanol vapor are combined (240) in a certain ratio to form a humidified fuel vapor which is presented to an anode (112) of the direct methanol fuel cell (110). The ratio of water to methanol can be adjusted automatically by a sensor (180) that monitors the current drawn by the load (170) on the fuel cell.

    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.
