Abstract: A ion-conductive composite membrane and a method of manufacturing the same, the membrane including phosphate platelets, a silicon compound, and a Keggin-type oxometalate and/or Keggin-type heteropoly acid, wherein the phosphate platelets are three-dimensionally connected to each other via the silicon compound and a method of manufacturing the same. An electrolyte membrane having an ion-conductive inorganic membrane or an ion-conductive organic/inorganic composite membrane effectively prevents crossover of liquid fuel without the reduction of ion conductivity in a liquid fuel cell, thereby allowing for the production of fuel cells having excellent performance.

Abstract: A switching device in a digital unit of a multi-sector base station, which uses switching elements incorporated in the digital unit and adapted to switch 3 sectors into multiple sectors, thereby being capable of implementing a multi-sector base station system allowing a softer handoff among all sectors. The switching elements are adapted to support the switching of the next channel element stage in the digital unit included in the existing 3-sector base station to implement a base station system, thereby allowing all handoff between sectors to be conducted in a softer handoff fashion while allowing all channel elements to be set for all sectors covered by the base station upon setting a traffic channel, thereby achieving an efficient allocation of channel elements.
