    Abstract: A method and apparatus for allocating channel bandwidths in a wireless IPTV system is provided. The method includes measuring, if an additional service offering request is received in a saturation channel state, remaining execution times until a service of each terminal that is currently receiving a service is terminated, and setting a minimum of the measured remaining execution times to a unit time; calculating a securable channel bandwidth per the unit time with respect to each terminal that is currently receiving a service; and allocating, if the summation of the securable channel bandwidths per the unit time is equal to or greater than a channel bandwidth required to provide the additional service, the requested channel bandwidth in order to provide the additional service.

    Abstract: Disclosed is a method of controlling a fuel cell system including a fuel processor to generate reforming gas and a stack to generate energy by receiving the reforming gas from the fuel processor. The method includes performing an initial operation, in which the fuel processor is operated to generate thermal energy heating, a heat medium is heated by the thermal energy generated from the fuel processor, and raising a temperature of the stack to a normal operation temperature by the heat medium having a high temperature, and performing a normal operation, in which the reforming gas is supplied to the stack after the temperature of the stack has reached the normal operation temperature. The stack temperature is raised until the stack is normally operated by heating the stack through the circulation of a heat medium heated by heat generated from a fuel processor.

    Abstract: Provided is a method of starting a polymer electrolyte membrane fuel cell (PEMFC) stack by rapidly increasing the temperature of the PEMFC stack. The PEMFC stack includes: a first flow line that is connected to upper parts of cooling plates installed in a plurality of unit cells of the PEMFC stack; a second flow line that is connected to lower parts of the cooling plates; a coolant reservoir installed between the first flow line and the second flow line; a heat exchanger installed between the first flow line and the coolant reservoir; a by-pass line that connects a point between the coolant reservoir and the second flow line, to the first flow line; a heating element that heats coolant in the by-pass line; a first valve installed between the first flow line and the heat exchanger; and a second valve that selectively connects the coolant reservoir, the second flow line, and the by-pass line. The method of starting a PEMFC stack includes: closing the first valve and controlling the second valve so that the second flow line and the by-pass line are connected to each other, and the coolant in the coolant reservoir is not connected to the second flow line and the by-pass line; and increasing the temperature of the PEMFC stack by heating the coolant in the by-pass line, using the heating element.
