    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: 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: A fuel cell (200) includes a membrane electrode assembly (210) located together with a layer of porous, Z-axis electrically conductive, positive temperature coefficient (PTC) material (250).

    Abstract: A small fuel cell (10) powers a portable electronic device (12) and contains a fuel reservoir (14) and a device (16) that measures the amount of liquid fuel (18) that is in the reservoir. The fuel cell operates on hydrogen that is obtained from a liquid hydrocarbon fuel, such as alcohol or other hydrocarbons. The liquid fuel is typically converted into hydrogen by a reforming process. The reservoir that is connected to the fuel cell has an indicia (19) that is readable by a human user of the portable electronic device, for measuring the amount of liquid hydrocarbon fuel that is present in the reservoir. Typically, the indicia consist of a sight glass, a capacitive element, a resistive element, a transparent portion of the reservoir, a float, or an acoustic transmitter coupled with an acoustic receiver.

    Abstract: Oxides of carbon and other impurities are removed from a hydrogen fuel supply stream (12) for a fuel cell (30). A getter element (20) sufficient for chemisorbing the oxides of carbon from the hydrogen is removably connected to the fuel cell anode side. The fuel stream is passed through the getter element so as to chemisorb the oxides of carbon onto the getter, thereby providing a purified stream of hydrogen (26) to the fuel cell anode. The getter is removed from the fuel cell when the getter when spent and replaced with a fresh getter.

    Abstract: A thermo-responsive polymer is incorporated into a fuel cell (50) in order to maintain optimum hydration of the polymer electrolyte membrane. The thermo-responsive polymer (52) is situated proximate to the membrane electrode assembly (54) such that fuel or oxidant gas passes (56) through the thermo-responsive polymer to the membrane electrode assembly. The thermo-responsive polymer swells or shrinks in response to changes in the operating temperature of the membrane electrode assembly, altering the flow rate of the fuel or oxidant gas passing through the thermo-responsive polymer.
