  • Publication number: 20070298290
    Abstract: A fuel cell power plant (10) includes a fuel cell (12) having a membrane electrode assembly (MEA) (16), disposed between an anode support plate (14) and a cathode support plate (18), the anode and/or cathode support plates include a hydrophilic substrate layer (80, 82) having a predetermined pore size. The pressure of the reactant gas streams (22, 24) is greater than the pressure of the coolant stream (26), such that a greater percentage of the pores within the hydrophilic substrate layer contain reactant gas rather than water. Any water that forms on the cathode side of the MEA will migrate through the cathode support plate and away from the MEA. Controlling the pressure also ensures that the coolant water will continually migrate from the coolant stream toward the anode side of the MEA, thereby preventing the membrane from becoming dry. Proper pore size and a pressure differential between coolant and reactants improves the electrical efficiency of the fuel cell.

  • Publication number: 20070014723
    Abstract: The present invention concerns methods and compositions for making and using Be complexes of defined compositions, which may have multiple functionalities and/or binding specificities. In various embodiment, Beryllium (Be) complexes may include Be such as 10Be and 7Be complexes. Such complexes find use in a wide variety of applications, particularly in the field of treatment, detection and/or diagnosis of infections, diseases and other health-related conditions, including but not limited to cancer, autoimmune disease, cardiovascular disease, metabolic diseases, degenerative diseases, and organ transplant rejection.

  • Publication number: 20060093879
    Abstract: A procedure for starting up a fuel cell system that is disconnected from its primary load and that has air in both its cathode and anode flow fields includes a) connecting an auxiliary resistive load across the cell to reduce the cell voltage; b) initiating a recirculation of the anode flow field exhaust through a recycle loop and providing a limited flow of hydrogen fuel into that recirculating exhaust; c) catalytically reacting the added fuel with oxygen present in the recirculating gases until substantially no oxygen remains within the recycle loop; disconnecting the auxiliary load; and then d) providing normal operating flow rates of fuel and air into respective anode and cathode flow fields and connecting the primary load across the cell. The catalytic reaction may take place on the anode or within a catalytic burner disposed within the recycle loop.

  • Publication number: 20060058245
    Abstract: Methods for therapy of cystic fibrosis and other conditions are provided. The methods comprise one or more agents capable of increasing thiol-containing compound transport via a transporter system (i.e. ABC transporters such as MDR-1 or MRP-2) in cells. Other embodiments include the use of agents to modulate transport of thiol-containing compounds within the cell. Therapeutic methods involve the administration of such agents to a patient afflicted with cystic fibrosis and/or another condition responsive to stimulation of thiol-containing compound transport.

  • Publication number: 20050147855
    Abstract: A procedure for starting up a fuel cell system that is disconnected from its primary load and has both its cathode and anode flow fields filled with air includes initiating a flow of air through the cathode flow field and rapidly displacing the air in the anode flow field by delivering a flow of fresh hydrogen containing fuel into the anode flow field, and thereafter connecting the primary load across the cell. Sufficiently fast purging of the anode flow field with hydrogen prior to connecting the cells to the load eliminates the need for purging the anode flow field with an inert gas, such as nitrogen, upon start-up.

  • Patent number: 5975057
    Abstract: A fuel injector control circuit and method include first switching circuitry (128, 134, 138, 142, 148, 152, 154) to selectively apply a first electrical signal (171) to a solenoid (114) to vary a load signal (176) between a first maximum (201) threshold and a first minimum (203) threshold. Second switching circuitry (130, 132, 136, 140, 148, 154) to selectively applies a second electrical signal (198) to the load (114) to vary the load signal (176) between a second maximum (205) threshold and a second minimum (207) threshold. The second electrical signal (198) has a magnitude substantially higher than the first electrical signal. Preferably, the second maximum threshold (205) has a magnitude less than a magnitude of the first maximum threshold (201), and greater than a magnitude of the first minimum threshold (203), and the second minimum threshold (207) has a magnitude less than the magnitude of the first minimum threshold (203).

  • Patent number: 5406049
    Abstract: The mirror assembly uses a non-reflective conductive coating as a heating element for preventing fog formation on a mirror exposed to a humid environment such as is found in a bathroom. As compared to conductive reflective mirror coatings, the non-reflective conductive coatings used in this invention have a relatively high resistance, which allows high reflectivity mirrors to be made fog-free. The conductive coatings may be split into separate conductive elements with one or more scribe lines in order to control the length of the conductive path from inlet bus to outlet bus. The buses may be made from an ultra thin foil tape, which can be adhered to the conductive coatings, and which is solderable for securement of power lines thereto. Such a bus tape possesses both in plane and through plane conductive characteristics and can easily be cut to any length desired for the mirror sizes being produced.

  • Patent number: 5083009
    Abstract: The mirror assembly uses a reflective coating as a heating element for preventing fog formation on a mirror exposed to a humid environment such as is found in a bathroom. As compared to other typically reflective mirror coatings, the coating used in this invention has a relatively high resistance. The coating may be split into separate conductive elements with one or more scribe lines in order to control the length of the conductive path from inlet bus to outlet bus. The buses are made from an ultra thin foil tape which can be adhered to the reflective coating and which is solderable for securement of power lines thereto. The bus tape possesses both in plane and through plane conductive characteristics and can simply be cut to any length desired for the mirror sizes being produced.
