  • Publication number: 20120094200
    Abstract: A method for starting operation of a solid polymer fuel cell from a temperature below 0° C. is disclosed that prevents certain problems with ice formation as the fuel cell thaws. During startup, the method involves providing the oxidant flow at a rate less than half of its maximum when the coolant temperature is near 0° C.

  • Publication number: 20110269057
    Abstract: Ruthenium or a Ruthenium compound is applied to an anode structure according to a predetermined pattern, with only part of the anode active area containing Ru. The parts of the MEA that do not contain Ru are not expected to suffer degradation from Ru cross-over, so that overall degradation of the cell will be diminished. Having less precious metals will also translate into less cost.

  • Patent number: 7392079
    Abstract: A system using neurological control signals to control a device is disclosed. The system may include a sensor sensing electrical activity of a plurality of neurons over time and a vector generator generating a neural control vector from the sensed electrical activity of the plurality of neurons over time. The system may also include a control filter to which the neural control vector is applied to provide a control variable and an output device controlled by the control variable.

  • Publication number: 20070248858
    Abstract: A fuel cell system comprising a fuel cell stack, a fuel recirculation line provided with a jet pump and a valve controlled by a control unit based on the anode-cathode pressure differential such that the valve is closed to reduce or stop fuel supply when the anode-cathode pressure differential reaches a predetermined value, and opened again to circulate more fuel through the jet pump when the pressure differential is below a predetermined value, to create a pulsed fuel supply that improves the fuel recirculation at low loads and ensures adequate water removal from the anode flow field channels.

  • Publication number: 20070207367
    Abstract: An electrochemical system is provided, the electrochemical system comprising a fuel cell stack, the fuel cell stack comprising at least one fuel cell, each fuel cell having at least one membrane electrode assembly interposed between an anode flow field plate and a cathode flow field plate, each membrane electrode assembly including an ion exchange membrane interposed between an anode electrode layer and a cathode electrode layer, wherein at least a portion of at least one of the anode electrode layers of the fuel cells is in fluid communication with an accumulating device. The accumulating device is operable to accumulate and dispense at least one of hydrogen, oxygen, and nitrogen. A method of ceasing operation of the electrochemical system is also disclosed.

  • Publication number: 20070087233
    Abstract: A system and method for implementing a fuel cell shutdown process are disclosed. Briefly described, one embodiment comprises establishing an oxidant recirculation path from a portion of the cathode flow path upon initiation of the fuel cell shutdown process, wherein the oxidant is recirculated during an oxygen depletion phase to substantially deplete oxygen residing therein to form a substantially oxygen-free fluid; and establishing an anode purge path from a portion of the cathode flow path and the anode flow path by means of a diverter valve, wherein the anode purge path is established upon completion of the oxygen depletion phase, and wherein the substantially oxygen-free fluid is transferred to the anode flow path to substantially purge out the fuel therein during a hydrogen purge phase.

  • Publication number: 20030105409
    Abstract: A continuous tracking task and multielectrode recording was used to describe position and velocity information encoding and decoding in primate motor cortex during visually guided hand motion. The pursuit tracking task (PTT) controls hand motion to remove statistical dependencies among kinematics and neural activity, provides reasonable data stationarity, and a broad sample of velocity and position space allowing description of the time varying features of MI tuning for hand motion. MI has a continuous contribution to visually guided hand motion. The amount of information for each cell was low and restricted to the slow components of movement. Decoding using a linear regression method confirms that position and velocity information can be recovered from the firing of ensembles of MI neurons and demonstrates that MI firing contains sufficient information to predict any future hand trajectory with moderate accuracy based on the firing patterns of small numbers of regionally associated MI neuron populations.
