  • Patent number: 7169491
    Abstract: A fuel cell system that routes anode effluent from one fuel cell stack to the anode side of another fuel cell stack to consume unused hydrogen in the production of electricity is disclosed. The routing of the anode effluent from one fuel cell stack to another is accomplished by providing flow paths that connect the anode sides of the various fuel cell stacks together. The flow paths contain valves that are operable to selectively block flow through the various flow paths as desired. Optionally, the flow paths can be operated free of any valves. Methods of operating such fuel cell systems are also disclosed.

  • Patent number: 7169492
    Abstract: Fuel cells are very well suited for the cogeneration of power and heat. An adaptation of the fuel cell power to the thermal requirement of the live load results in faulty adaptations and efficiency losses if the thermal requirement fluctuates significantly. The invention aims to achieve a continuous and lossless adaptation of the thermal production of the fuel cell to the current thermal requirement. The invention utilizes the fact that fuel cells are continuously adjustable over a broad load range. The invention proposes a continuous control of the current based on the supply or return temperature of the thermal circuit. According to the invention, a control method is used that has a quasi-continuous characteristic, particularly a control according to a PID-algorithm with additional limitation of the current as a control variable with respect to the minimum and the maximum value and of the amount of the time rate of change of the current.

  • Patent number: 7169495
    Abstract: A thermally integrated fuel cell system includes a stack zone, a burner zone and a low temperature zone. The fuel is combined with steam and passed sequentially through a primary reformer and a secondary reformer. Air is split into two parallel streams and preheated in a low temperature heat exchanger. One air stream passes to a high temperature heat exchanger while the other passes to a radiative heat exchanger. The air and fuel streams are equalized in an equalization heat exchanger before entering the fuel cell stacks. The stack exhaust is combusted in an afterburner. Afterburner exhaust heats the primary reformer, the high temperature heat exchanger, the low temperature heat exchanger and steam generator. The stack zone includes the stacks, the secondary reformer, the radiative heat exchanger and the equalization heat exchanger. The burner zone includes the afterburner, the primary reformer and the high temperature heat exchanger.

  • Patent number: 7169536
    Abstract: A manufacturing method for a field emission display includes the steps of (1) forming a conductive film on a substrate that is to be a base plate, the conductive film being for forming a cathode electrode; (2) applying, on the conductive film, a positive resist, which is a photosensitive material; (3) exposing the positive resist to light, so as to form openings that correspond in a shape of emitters, the light being (a) emitted from a light source, (b) paralleled so that rays thereof have even light intensity distribution, and (c) directed into a micro lens array so as to be condensed in interior of the photosensitive material; and (4) forming the emitters respectively in the openings. This arrangement provides a manufacturing method for a field emission display, the method capable of highly accurately and highly productively sharp emitters aligned orderly, without a complicate manufacturing step and a complicate optical system.
