    摘要: A method for operating a polymer electrolyte membrane fuel cell at temperatures below the freezing point of water and an apparatus thereof are provided to prevent damage and performance degradation of the membrane-electrode assemblies. Non-humidified gas flows for several seconds before temperature of the polymer electrolyte membrane fuel cell falls below the freezing temperature of water when operation of the polymer electrolyte membrane fuel cell stops. Simultaneously, anode of the polymer electrolyte membrane fuel cell is filled with a solution having a low freezing point to prevent the temperature of a polymer electrolyte membrane fuel cell falling below the freezing point of water due to the lower ambient temperature in the winter. When the polymer electrolyte membrane fuel cell is restarted, the cell performance is not degraded reflecting that the present invention stably preserves the fuel cell.

    摘要: A multi-dimensional optical cross-connect switching system. The system is capable of multi-dimensionally using wavelength resources, such as in the forms of optical fibers, optical wavelength bands and optical wavelengths. The system can three-dimensionally use the wavelength resources by being matched with an optical transport network through the optical fiber layer, optical wavelength band layer and optical wavelength layer. In addition, the multi-dimentional optical cross-connect switching system is constructed in such a way that two cross-connect switches are symmetrically arranged and an insertion/extraction switch is added to switch addition/dropping links between the two switches.

    摘要: An optical packet header processing apparatus for processing a header of an optical packet expressing an address of a destination node to control a switching operation of an optical packet switch. The optical packet header processing apparatus comprises a beam splitter for splitting the optical packet header into a predetermined number of optical packet header elements, and a plurality of time interval detectors. Each of the time interval detectors receives a corresponding one of the optical packet header elements from the beam splitter and outputs a detect optical pulse if a pair of optical pulses having a predetermined time interval therebetween are present in the received optical packet header element. A plurality of optical pulse detectors are adapted to convert the detect optical pulses from the time interval detectors into electrical signals and transfer the converted electrical signals to the optical packet switch, respectively. Therefore, the optical packet switch determines the destination node in response to the electrical signals from the optical pulse detectors and outputs the optical packet to an output port corresponding to the determined destination node.

    摘要: An optical switch selectively transmits an optical signal to one of multiple optical paths for use in an optical communication. The optical switch includes a mobile structure provided with a mirror surface at one end surface of the mobile structure to change the optical path by moving the mobile structure backward and forward along an axis parallel to the mirror surface. It has at least a pair of leaf springs in the form of a shallow arch, wherein each of the leaf springs is connected to both side surfaces of the mobile structure in a leaf spring axis perpendicular to the mirror surface, respectively, thereby obtaining a latch-up function and an actuator for moving the mobile structure. In the optical switch, elastic bodies are introduced into connection portions of the leaf springs, respectively, to give rise to a degree of freedom to the connection portions in the direction of the leaf spring axis. The elastic body can be an I-shape beam, a multiple spring with a curvature and an S-shape beam allowing angle deflection.
